Low Mass Companions for Five Solar-Type Stars from the Magellan Planet Search Program
Dante Minniti, R. Paul Butler, Mercedes Lopez-Morales +5
We report low mass companions orbiting five Solar-type stars that have emerged from the Magellan precision Doppler velocity survey, with minimum (Msini) masses ranging from 1.2 to…
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…
How eccentric orbital solutions can hide planetary systems in 2:1 resonant orbits
Guillem Anglada-Escude, Mercedes Lopez-Morales, John E. Chambers
The Doppler technique measures the reflex radial motion of a star induced by the presence of companions and is the most successful method to detect exoplanets. If several planets a…
A Second Look at the Metal Line Variability of G29-38
J. H. Debes, M. Lopez-Morales
The pulsating white dwarf G29-38 possesses a dust disk and metal lines attributed to the accretion of its disk material. \citet{vonhipg29} have reported variability in the equivale…
