SEEDS direct imaging of the RV-detected companion to V450 Andromedae, and characterization of the system
K. G. Hełminiak, M. Kuzuhara, K. Mede +49
We report the direct imaging detection of a low-mass companion to a young, moderately active star V450 And, that was previously identified with the radial velocity method. The comp…
Very Low-Mass Stellar and Substellar Companions to Solar-like Stars From MARVELS VI: A Giant Planet and a Brown Dwarf Candidate in a Close Binary System HD 87646
Bo Ma, Jian Ge, Alex Wolszczan +34
We report the detections of a giant planet (MARVELS-7b) and a brown dwarf candidate (MARVELS-7c) around the primary star in the close binary system, HD 87646. It is the first close…
Thermal Infrared Imaging and Atmospheric Modeling of VHS J125601.92-125723.9 b: Evidence for Moderately Thick Clouds and Equilibrium Carbon Chemistry in a Hierarchical Triple System
Evan A. Rich, Thayne Currie, John P. Wisniewski +5
We present and analyze Subaru/IRCS L' and M' images of the nearby M dwarf VHS J125601.92-125723.9 (VHS 1256), which was recently claimed to have a ~11 M_Jup companion (VHS 1256 b)…
Disk Detective: Discovery of New Circumstellar Disk Candidates through Citizen Science
Marc J. Kuchner, Steven M. Silverberg, Alissa S. Bans +23
The Disk Detective citizen science project aims to find new stars with 22 micron excess emission from circumstellar dust using data from NASA's WISE mission. Initial cuts on the Al…
Constraining the Movement of the Spiral Features and the Locations of Planetary Bodies within the AB Aur System
Jamie R. Lomax, John P. Wisniewski, Carol A. Grady +54
We present new analysis of multi-epoch, H-band, scattered light images of the AB Aur system. We used a Monte Carlo, radiative transfer code to simultaneously model the system's SED…
Kepler Flares IV: A Comprehensive Analysis of the Activity of the dM4e Star GJ 1243
Steven M. Silverberg, Adam F. Kowalski, James R. A. Davenport +3
We present a comprehensive study of the active dM4e star GJ 1243. We use previous observations and ground-based echelle spectroscopy to determine that GJ 1243 is a member of the Ar…
