*Tri*Star* – The Triad Starfest

*TRI*STAR* 2019

TriStar 2019 Logo The Triad Starfest, *Tri*Star* for short, is a conference of astronomers of all types, from novice to professional, for a full day of presentations, displays, and observing. The event allows astronomy enthusiasts to share ideas, learn about a range of astronomical topics, get together with old friends, and make new ones. The event draws astronomers from North Carolina and surrounding states. 

*Tri*Star* is free and open to anyone with an interest in astronomy. There is a change in venue for this year’s edition of *Tri*Star*.  Becaise of ongoing renovation at GTCC, our traditional space in the Applied Technologies Center is not available, so we are shifting across campus to the Koury Hospitality Careers Center, site of our annual Jo Cline Memorial Lecture in the fall.  Koury is Building 19 on this Campus Map.  Park in Lot F.

*Tri*Star* 2019 will be held Saturday, March 2 and will feature a series of speakers scheduled throughout the day, as well as a wide range of astronomical displays, assorted astronomy-related vendors, prize drawings, "how-to" help for astronomy beginners, an astroimaging contest, and daytime and nighttime observing sessions. 

In addition to Saturday’s agenda, *Tri*Star* always includes a special Friday evening presentation held in the Koury Auditorium (the same location as Saturday’s activities).  Our 2019 featured speaker is Stella Kafka, director of the American Association of Variable Star Observers.  Her Friday presentation, "Variable Stars and their Stories"  begins at 7:00 p.m.  Cline Observatory will be open for observing after the talk, weather permitting.

Note: In case inclement weather causes the Jamestown Campus of GTCC to be closed on the date of *Tri*Star*, please monitor campus status before coming to GTCC. Information is available at the GTCC web page, on Twitter, or by dialing the GTCC switchboard at 336-334-4822.

Pre-*Tri*Star* Lecture

Auditorium, Koury Hospitality Careers Center, GTCC
Stella Kafka, Director, AAVSO

Variable Stars and their Stories

Variable stars have always been the most intriguing (and fun) targets for observers, professional and amateur alike. Stellar variability, both intrinsic and extrinsic, provides unique insights in critical stages of stellar evolution, help determine distances to nearby galaxies and add to our understanding of explosion physics and chemical enrichment of the Milky Way.

I will introduce some of the most common aspects of stellar variability and their significance in astrophysics. I will discuss their common light curves identifiers, and present work by AAVSO observers that has led to cutting-edge scientific discoveries throughout the years. Finally, I will discuss how you can participate in variable star observations from your back yard, contributing to the AAVSO International Database and to cutting-edge science.
