Stellar Parameters for HD 69830, a Nearby Star with Three Neptune Mass Planets and an Asteroid Belt
Angelle Tanner, Tabetha S. Boyajian, Kaspar von Braun +9
We used the CHARA Array to directly measure the angular diameter of HD 69830, home to three Neptune mass planets and an asteroid belt. Our measurement of 0.674+/-0.014 milli-arcsec…
The non-thermal superbubble in IC 10: the generation of cosmic ray electrons caught in the act
Volker Heesen, Elias Brinks, Martin G. H. Krause +6
Superbubbles are crucial for stellar feedback, with supposedly high (of the order of 10 per cent) thermalization rates. We combined multiband radio continuum observations from the…
IN-SYNC II: Virial Stars from Sub-Virial Cores -- The Velocity Dispersion of Embedded Pre-Main-Sequence Stars in NGC 1333
Jonathan B. Foster, Michiel Cottaar, Kevin R. Covey +14
The initial velocity dispersion of newborn stars is a major unconstrained aspect of star formation theory. Using near-infrared spectra obtained with the APOGEE spectrograph, we sho…
Stellar Diameters and Temperatures VI. High angular resolution measurements of the transiting exoplanet host stars HD 189733 and HD 209458 and implications for models of cool dwarfs
Tabetha Boyajian, Kaspar von Braun, Gregory A. Feiden +24
We present direct radii measurements of the well-known transiting exoplanet host stars HD 189733 and HD 209458 using the CHARA Array interferometer. We find the limb-darkened angul…
Planets Around Low-Mass Stars (PALMS). IV. The Outer Architecture of M Dwarf Planetary Systems
Brendan P. Bowler, Michael C. Liu, Evgenya L. Shkolnik +1
We present results from a high-contrast adaptive optics imaging search for giant planets and brown dwarfs (>1 MJup) around 122 newly identified nearby (<40 pc) young M dwarfs. Half…
Herschel/PACS view of disks around low-mass stars and brown dwarfs in the TW Hya association
Yao Liu, Gregory J. Herczeg, Munan Gong +6
We conducted Herschel/PACS observations of five very low-mass stars or brown dwarfs located in the TW Hya association with the goal of characterizing the properties of disks in the…
