The eclipsing binary GU Mon is located in the star-forming cluster Dolidze 25, which has the lowest metallicity measured in a Milky Way young cluster. Aims. GU Mon has been identified as a short-period eclipsing binary with two early B-type components. We set out to derive its orbital and stellar parameters. Methods. We present a comprehensive analysis, including B and V light curves and 11 high-resolution spectra, to verify the orbital period and determine parameters. -

On the Development and Applications of Automated Searches for Eclipsing Binary Stars A thesis presented by Jonathan Devor to The Department of Astronomy in partial fulfillment of the requirements for the degree of Doctor of Philosophy in the subject of arXiv:0811.0017v1 [astro-ph] 3 Nov 2008 Astronomy Harvard University Cambridge, Massachusetts 13 February 2008 c 2008, by Jonathan Devor All rights reserved. Dissertation Advisor: Prof. David B. Charbonneau Jonathan Devor On the Development and Applications of Automated Searches for Eclipsing Binary Stars Abstract Eclipsing binary star systems provide the most accurate method of measuring both the masses and radii of stars. Moreover, they enable testing tidal synchronization and circularization theories, as well as constraining models of stellar structure and dynamics. With the recent availability of large-scale multi-epoch photometric datasets we were able to study eclipsing binary stars en masse. In this thesis, we analyzed 185,445 light curves from ten TrES fields, and 218,699 light curves from the OGLE II bulge fields. In order to manage such large quantities of data, we developed a pipeline with which we systematically identified eclipsing binaries, solved for their geometric orientations, and then found their components’ absolute properties. Following this analysis we assembled catalogs of eclipsing binaries with their models, computed statistical distributions of their properties, and located rare cases for further follow-up, including T-Cyg1-03378, which has unusual eclipse timing variations. Of particular importance are low-mass eclipsing binaries, which are rare yet critical for resolving the ongoing mass-radius discrepancy between theoretical models and observations. -

I hope everybody had a fun Mardi Gras and is getting ready for the coming Spring and the galaxies that come into view with it. Unfortunately, that also means that the scourge of Daylight Saving Time is also upon us, and with new bills in the Louisiana legislature proposing a permanent switch to DST, I, for one, hope you take a moment to write, call, or visit with your elected representative to suggest their doing away with it altogether instead.
