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…
The Future Evolution of White Dwarf Stars Through Baryon Decay and Time Varying Gravitational Constant
Jacob A. Ketchum, Fred C. Adams
Motivated by the possibility that the fundamental ``constants'' of nature could vary with time, this paper considers the long term evolution of white dwarf stars under the combined…
Eccentricity evolution of giant planet orbits due to circumstellar disk torques
Althea V. Moorhead, Fred C. Adams
The extrasolar planets discovered to date possess unexpected orbital elements. Most orbit their host stars with larger eccentricities and smaller semi-major axes than similarly siz…
Calibration of the Relationship between Precipitable Water Vapor and 225 GHz Atmospheric Opacity via Optical Echelle Spectroscopy at Las Campanas Observatory
Joanna Thomas-Osip, Andrew McWilliam, M. M. Phillips +4
We report precipitable water vapor (PWV) measurements made at Las Campanas Observatory using optical spectra of H2O lines obtained with the Magellan echelle spectrograph, and calcu…
Baryonic Collapse within Dark Matter Halos and the Formation of Gaseous Galactic Disks
Fred C. Adams, Anthony M. Bloch
This paper constructs an analytic framework for calculating the assembly of galactic disks from the collapse of gas within dark matter halos, with the goal of determining the surfa…
