StarClock: Stellar evolution at PC

This is an excellent program for anyone wanting to learn
more about how stars change as they age.
StarClock is now a staple in my astronomy software list.

HR diagram movie This short movie, based on StarClock 2.0, shows the evolution of a five-solar-mass star.

StarClock 2.0 (precisely the file, about 120k) is currently available at the following sites:

This WWW page (Masaryk University, Brno, Czech Republic).
SEDS (Students for the Exploration and Development of Space, Arizona, USA)
SimTel, the Coast to Coast Software Repository (tm) and its numerous mirror sites.
Short reviews of StarClock appeared in Sky & Telescope (Ver. 1.0, April 1996, p. 55) and Astronomy (Ver. 2.0, June 1996, p. 94).

StarClock could have never been created if it were not for the grid of stellar models computed by G. Schaller, D. Schaerer, G. Meynet and A. Maeder (Geneva Observatory) and published in a form which called for writting the program. I am grateful to Nancy R. Evans (York University) and Mirek J. Plavec (University of California, Los Angeles) for providing me with the real stars data. My thanks go to all users (mainly teachers of astronomy or physics) who shared their experience with StarClock 1.0. Their responses encouraged me to finish this second, much extended and hopefully better version. I acknowledge help of Rudolf Novak, Jenik Hollan and Jan Janca with the code. The online services of CDS (Strasbourg, France) proved to be quite useful. StarClock 2.0 was developed on computers of the Department of Theoretical Physics and Astrophysics (DTPA) of the Masaryk University Brno, and the Nicholas Copernicus Observatory and Planetarium Brno. I thank both the institutions and especially Jarek Kucera (formerly DTPA) for hospitality.
