The Cephei System: Updated Orbits, Dynamical Architecture, and Limits on Additional Companions

Judah Van Zandt, Brendan P. Bowler, Michael Endl +18

The Cephei system hosts one of the first exoplanets discovered and is orbited by one of the closest known stellar companions to a planet-hosting star. Here, we derive updated o…

TIC 295741342: A Triply-Eclipsing Triple Star System with a Giant Tertiary

Brian P. Powell, Guillermo Torres, Veselin B. Kostov +4

We present the discovery and characterization of TIC 295741342, a triply-eclipsing triple star system with a giant tertiary. The eclipsing binary consists of two similar main-seque…

Long-term Spectroscopic Survey of the Hyades Cluster: The Binary Population

Guillermo Torres, Robert P. Stefanik, David W. Latham

We report the results of a radial velocity monitoring program in the Hyades region, carried out at the Center for Astrophysics over a period of more than 45 yr. Nearly 12,000 spect…

A transiting multi-planet system in the 61 million year old association Theia 116

Sydney Vach, George Zhou, Chelsea X. Huang +28

Observing and characterizing young planetary systems can aid in unveiling the evolutionary mechanisms that sculpt the mature exoplanet population. As an all-sky survey, NASA's Tran…

Orbits and Dynamical Masses for Six Binary Systems in the Hyades Cluster

Guillermo Torres, Gail H. Schaefer, Robert P. Stefanik +8

We report long baseline interferometric observations with the CHARA Array that resolve six previously known double-lined spectroscopic binary systems in the Hyades cluster, with or…

Orbits and Dynamical Masses for the Active Hyades Multiple System HD 284163

Guillermo Torres, Gail H. Schaefer, Robert P. Stefanik +16

We report near-infrared long-baseline interferometric observations of the Hyades multiple system HD 284163, made with the CHARA array, as well as almost 43 yr of high-resolution sp…

Dynamical Masses for the Hyades Binary System vB 120

Guillermo Torres, Robert P. Stefanik, David W. Latham

We report spectroscopic observations of vB 120 (HD 30712), a 5.7 yr astrometric-spectroscopic binary system in the Hyades cluster. We combine our radial velocities with others from…

Masses, Radii, and Orbits of Small Kepler Planets: The Transition from Gaseous to Rocky Planets

Geoffrey W. Marcy, Howard Isaacson, Andrew W. Howard +100

We report on the masses, sizes, and orbits of the planets orbiting 22 Kepler stars. There are 49 planet candidates around these stars, including 42 detected through transits and 7…

HAT-P-27b: A hot Jupiter transiting a G star on a 3 day orbit

Bence Béky, Gáspár Á. Bakos, Joel Hartman +21

We report the discovery of HAT-P-27b, an exoplanet transiting the moderately bright G8 dwarf star GSC 0333-00351 (V=12.214). The orbital period is 3.039586 +/- 0.000012 d, the refe…

Refined stellar, orbital and planetary parameters of the eccentric HAT-P-2 planetary system

András Pál, Gáspár Á. Bakos, Guillermo Torres +10

We present refined parameters for the extrasolar planetary system HAT-P-2 (also known as HD 147506), based on new radial velocity and photometric data. HAT-P-2b is a transiting ext…
