Eclipsing Binary Stars as Tests of Stellar Evolutionary Models and Stellar Ages
Keivan G. Stassun, Leslie Hebb, Mercedes Lopez-Morales +1
Eclipsing binary stars provide highly accurate measurements of the fundamental physical properties of stars. They therefore serve as stringent tests of the predictions of evolution…
Ground-based secondary eclipse detection of the very-hot Jupiter OGLE-TR-56b
David K. Sing, Mercedes Lopez-Morales
We report on the detection of the secondary eclipse of the very-hot Jupiter OGLE-TR-56b from combined z-band time series photometry obtained with the VLT and Magellan telescopes. W…
Transit Timing Observations of the Extrasolar Hot-Neptune Planet GL 436b
Guy S. Stringfellow, Jeffrey L. Coughlin, Mercedes López-Morales +4
Gliese 436 is an M dwarf with a mass of 0.45 Msun and hosts the extrasolar planet GL 436b [3, 6, 7, 2], which is currently the least massive transiting planet with a mass of ~23.17…
New Observations and a Possible Detection of Parameter Variations in the Transits of Gliese 436b
Jeffrey L. Coughlin, Guy S. Stringfellow, Andrew C. Becker +3
We present ground-based observations of the transiting Neptune-mass planet Gl 436b obtained with the 3.5-meter telescope at Apache Point Observatory and other supporting telescopes…
Fundamental Properties of Low-Mass Stars and Brown Dwarfs
Michael C. Liu, Keivan G. Stassun, France Allard +7
Precise measurements of the fundamental properties of low-mass stars and brown dwarfs are key to understanding the physics underlying their formation and evolution. While there has…
Two Jupiter-Mass Planets Orbiting HD 154672 and HD 205739
Mercedes Lopez-Morales, R. Paul Butler, Debra A. Fischer +6
We report the detection of the first two planets from the N2K Doppler planet search program at the Magellan telescopes. The first planet has a mass of M sin i = 4.96 M_Jup and is o…
