Vorocube © Bathsheba Grossman (www.bathsheba.com). The sculpture reminds me of the way acoustic waves reflect off the surface of an oscillating star.

Astroseismology is the study of internal stellar structure through observation and interpretation of acoustic oscillations that appear as small periodic irregularities in light and spectra of some stars. I rather like to think that astroseismology is simply: listening to how the stars sing. :)

Roche potential of a close binary, a crossection through L₁.

Half of all the stars in the night sky are actually close binary systems - stars in pairs so tight that they sometimes touch, or even embrace in common envelopes. If astroseismology is a study on how the stars sing, through the study of close binaries we learn how they dance. :)

A model and the Eclipse Mapping reconstruction of the light patterns produced by three modes in a non-radially oscillating star.

Pulzem is a software suite for analysis of nonradial oscillations on stars in eclipsing binary systems, created and maintained by Barna I. Biro from Baja Astronomical Observatory.

My role so far has been testing and application; in the future I hope to contribute by improving the modeling aspects of the program.

PHOEBE stands for PHysics Of Eclipsing BinariEs.It is a program for analysis of photometric and spectroscopic data from eclipsing binaries, created and maintained by Andrej Prsa from Villanova University.

My involvement with this project is primarily GUI development and documentation.

AstroPlot is a project by Attila and me. It's a small program for plotting 2D data, slightly oriented towards drawing astronomical spectra. It is free, so go ahead and download the installer and/or the source from our GoogleCode webspace. For a sort of scientific rationale, see the add. :)

ISAAC is a program for analysis of astronomical spectra. Attila and I wrote it in 2002, and rewrote it in 2003; later we abandoned its development in favor of AstroPlot. ISAAC is mentioned in this presentation, and described in detail on this poster. We used it for research presented in 2003 and 2005.
