    EXTREMELY EXTENDED DUST SHELLS AROUND EVOLVED INTERMEDIATE MASS STARS: PROBING MASS LOSS HISTORIES,THERMAL PULSES AND STELLAR EVOLUTION A Thesis presented to the Faculty of the Graduate School at the University of Missouri In Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy by BASIL MENZI MCHUNU Dr. Angela K. Speck December 2011 The undersigned, appointed by the Dean of the Graduate School, have examined the dissertation entitled: EXTREMELY EXTENDED DUST SHELLS AROUND EVOLVED INTERMEDIATE MASS STARS PROBING MASS LOSS HISTORIES, THERMAL PULSES AND STELLAR EVOLUTION USING FAR-INFRARED IMAGING PHOTOMETRY presented by Basil Menzi Mchunu, a candidate for the degree of Doctor of Philosophy and hereby certify that, in their opinion, it is worthy of acceptance. Dr. Angela K. Speck Dr. Sergei Kopeikin Dr. Adam Helfer Dr. Bahram Mashhoon Dr. Haskell Taub DEDICATION This thesis is dedicated to my family, who raised me to be the man I am today under challenging conditions: my grandfather Baba (Samuel Mpala Mchunu), my grandmother (Ma Magasa, Nonhlekiso Mchunu), my aunt Thembeni, and my mother, Nombso Betty Mchunu. I would especially like to thank my mother for all the courage she gave me, bringing me chocolate during my undergraduate days to show her love when she had little else to give, and giving her unending support when I was so far away from home in graduate school. She passed away, when I was so close to graduation. To her, I say, ′′Ulale kahle Macingwane.′′ I have done it with the help from your spirit and courage. I would also like to thank my wife, Heather Shawver, and our beautiful children, Rosemary and Brianna , for making me see life with a new meaning of hope and prosperity.

On leaving the planetarium, turn around and look northwards over the roof of the building. To your right is a group of stars like the outline of a saucepan standing up on it’s handle. This is the Plough (also called the Big Dipper) and is part of the constellation Ursa Major, the Great Bear. The top two stars are called the Pointers. Check with binoculars. Not all stars are white. The colour shows that Dubhe is cooler than Merak in the same way that red-hot is cooler than white-hot. 2. Use the Pointers to guide you to the left, to the next bright star. This is Polaris, the Pole (or North) Star. Note that it is not the brightest star in the sky, a common misconception. Below and to the right are two prominent but fainter stars. These are Kochab and Pherkad, the Guardians of the Pole. Look carefully and you will notice that Kochab is slightly orange when compared to Polaris. Check with binoculars. © Rob Peeling, CaDAS, 2007 version 2.0 Wynyard Planetarium & Observatory PUBLIC OBSERVING – Winter Polaris, Kochab and Pherkad mark the constellation Ursa Minor, the Little Bear.

    Thursday, December 22Nd Swap Meet & Potluck Get-Together Next First

    Io – December 2011 p.1 IO - December 2011 Issue 2011-12 PO Box 7264 Eugene Astronomical Society Annual Club Dues $25 Springfield, OR 97475 President: Sam Pitts - 688-7330 www.eugeneastro.org Secretary: Jerry Oltion - 343-4758 Additional Board members: EAS is a proud member of: Jacob Strandlien, Tony Dandurand, John Loper. Next Meeting: Thursday, December 22nd Swap Meet & Potluck Get-Together Our December meeting will be a chance to visit and share a potluck dinner with fellow amateur astronomers, plus swap extra gear for new and exciting equipment from somebody else’s stash. Bring some food to share and any astronomy gear you’d like to sell, trade, or give away. We will have on hand some of the gear that was donated to the club this summer, including mirrors, lenses, blanks, telescope parts, and even entire telescopes. Come check out the bargains and visit with your fellow amateur astronomers in a relaxed evening before Christmas. We also encourage people to bring any new gear or projects they would like to show the rest of the club. The meeting is at 7:00 on December 22nd at EWEB’s Community Room, 500 E. 4th in Eugene. Next First Quarter Fridays: December 2nd and 30th Our November star party was clouded out, along with a good deal of the month afterward. If that sounds familiar, that’s because it is: I changed the date in the previous sentence from October to November and left the rest of the sentence intact. Yes, our autumn weather is predictable. Here’s hoping for a lucky break in the weather for our two December star parties.
