Mt John Observatory – Weekend with the stars

As staff of UC you are also considered part of the UC Alumni Community. We would like to invite you to attend our alumni weekend trip to Mt John on Saturday 29 – Sunday 30 April 2017.

An example of the weekend programme can be seen below, please note that places are limited and this event usually books out within a week.

Mount John Observatory, Alumni Trip April
Mount John Observatory

Programme:
The afternoon starts at 12.45pm Saturday, with a daytime tour of the facilities followed by afternoon tea at the Observatory. We then head down the mountain for some presentations on Astronomy, and dinner.

The buffet dinner will be held after the presentation, we then return to the Observatory where you will be given the opportunity to view the night sky through one of the telescopes (please note that star viewings are weather dependent*).

On Sunday morning we will be joined by Graeme Murray for a geography/nature walk around the Mt John Summit Track, this is  a great way to learn the history of the area. This is the end of our weekend’s activities.

Cost: $115 per person Register here

Please note:
1. Travel: You will need to organise your own travel to and from Tekapo.
2. Accommodation: Accommodation is not included in the price of this tour. Check out the accommodation providers on the Tekapo Tourism site.
3.*Weather conditions: While this is the optimum time of year to visit, the visibility of the stars is still dependent on weather. In the event of cloudy weather, we have an inside lecture after dinner instead. (This happens around once in every three trips. Please note that we cannot refund the payment as it goes towards dinner and the upkeep of Mt John/use of facilities).
4.Group numbers: Due to space constraints of the telescopes and the observatory facilities, and to ensure everyone enjoys a quality experience, the maximum number for this event is 50 people. Registration will close when we reach the allotted number, and you may only register for yourself and one guest.
5. Age of attendees: The recommended minimum age for attendees is 16 years.

Any questions, please email samantha.boon@canterbury.ac.nz

Visiting Mt John over Summer?

If you are heading down South over the holiday season, be sure to take your UC staff ID, so you can use it for free access on the toll road to Mt John.

Mt John Observatory at the northern end of the Mackenzie Basin, near Lake Tekapo, is New Zealand’s premier astronomical research observatory.

A Mexican Adventure

Professor John Hearnshaw recently participated in the 98th Executive Committee (EC) meeting of the International Astronomical Union (IAU) in Mexico City. Read more about his Mexican adventure below.


For those unfamiliar with the IAU, it is the worldwide organisation for professional astronomers, with about 10,300 active members in 73 countries which are in turn national members of the Union. A few more individual members are from countries that do not adhere to the IAU.

The EC comprises nine members, including the President, Silvia Torres who is from Mexico, a General Secretary (Piero Benvenuti, from Italy) and Assistant General Secretary and half a dozen vice-presidents. The IAU has recently been restructured into nine divisions, each with its own president and steering committee. In my case I am president of IAU Division C for Education, Outreach and Heritage. In fact Division C also deals with the history of astronomy. The nine division presidents were also invited to participate in the EC98 meeting, making 18 people to sit round the board table (although one of the nine Division Presidents was incapacitated at last minute and couldn’t attend).

It was a fascinating experience to delve into the inner workings of the IAU. The topics discussed were the work of the divisions, the proposals for IAU Symposia to be held in 2017 (nine were selected from 33 applications), the formation and approval of working groups, which are set up by division presidents to tackle a huge variety of tasks within each division. The IAU operates in addition to the divisions, three offices with special funding and professional staff. They are the Office of Astronomy for Development (OAD) in Cape Town (promoting astronomy in developing countries), the Office for Astronomy Outreach (OAO) in Tokyo, which coordinates outreach activities of astronomy for the public, and the Office for Young Astronomers (OYA) in Oslo, which runs one or two three-week long schools for young astronomers, generally graduate students, every year and usually in developing countries.  This year’s International School for Young Astronomers (ISYA) will be in Tehran in September.

As President of Division C, I had an oversight role for all three offices of the IAU. Of course the EC also discussed topics such as finance and the IAU budget, and a major subject was preparations for the next General Assembly of the IAU, to be held in Vienna in August 2018. It will be an important General Assembly as the IAU will be nearly 100 years old then (it was formed in 1919, so plans for a major celebration of the centenary are being made. About 2500 to 3000 astronomers are expected to converge on Vienna in just over two years’ time.

So all these meetings were going on over three days. As I am also President of the Royal Astronomical Society of NZ, it is interesting to make a comparison between the national and international organisations. In a sense the meetings of the Council of RASNZ, also held face-to-face once a year, are a little bit like the IAU EC meetings. The same sorts of issues come up: funding, work of the divisions (or sections as we call them in RASNZ), how to bring more young astronomers in as members, and so on; it’s just that the IAU is an organization some 50 times larger than RASNZ, so the issues are inevitably a lot more complex, especially as the IAU has to embrace so many different national cultures. Fortunately (for me at least) all the discussions are held in English, the international language of science.

Although we had three solid days of meetings, two further days were devoted to cultural tours in Mexico City, included one to the amazing Teotihuacán pyramids, the site of an ancient city that thrived from 100 BC to 750 AD and occupied by about 200,000 people of uncertain ethnicity. It is a truly extraordinary place.
And we also had two amazing banquets in two of Mexico City’s top restaurants, hosted by the IAU President Silvia Torres and by the Director of the Mexican Institute of Astronomy, Jesús González. So all this was an amazing experience; unfortunately for me the excitement of Mexico was somewhat tempered by developing a tooth infection necessitating two visits to a private hospital for dental treatment. That’s another story – all I will say is that Mexico’s top private hospital was an amazing place equipped with all the latest gadgetry for medical interventions.

My term as IAU Division C president extends for another two and a half years, and the work so far has been remarkably busy – helping to select symposia to be supported in 2017 (nine were funded from 33 applications); establishing 17 different working groups to tackle a wide range of tasks in education, outreach and heritage; accepting nine new associate members to work with Division members; tackling two cases of alleged harassment, one of which has led to contentious litigation and the cancellation of an IAU symposium on astronomy education after most of the organizing committee resigned; proposing and having accepted a new symposium to replace it. No doubt the next year will bring an equally diverse range of matters for the Division’s steering committee to consider.

The Life and Death of Intermediate-mass Stars – Astronomy Candidate Seminar

When: Wednesday 18 May, 11:00 am – 12:00 pm 

Where: Rutherford 701,  Level 7


 

Dr David Frew from the Department of Physics, The University of Hong Kong (candidate for the position of Lecturer in Astronomy) will present: The Life and Death of Intermediate-mass Stars.

Following is an overview from Dr David Frew:

I will present an overview of our present understanding of the late-stage evolution of intermediate-mass stars (~ 1 to 8 times the mass of our Sun). Both single stars and those in binary systems will be examined. I will pay particular attention to the post-red giant phase(s) of evolution, when most of a star’s mass is ejected into the ambient interstellar medium. The physical and chemical characteristics of the “planetary nebulae” that are formed at this point in a star’s life provide insights into the many processes governing both stellar death and Galactic enrichment. I will conclude this talk by outlining current and future research questions in this field of astrophysics.

Everyone is welcome.
