On-sky performance of the QACITS pointing control technique with the Keck/NIRC2 vortex coronagraph
Elsa Huby, Michael Bottom, Bruno Femenia +4
A vortex coronagraph is now available for high contrast observations with the Keck/NIRC2 instrument at L band. Reaching the optimal performance of the coronagraph requires fine con…
The W. M. Keck Observatory infrared vortex coronagraph and a first image of HIP79124 B
Eugene Serabyn, Elsa Huby, Keith Matthews +22
An optical vortex coronagraph has been implemented within the NIRC2 camera on the Keck II telescope and used to carry out on-sky tests and observations. The development of this new…
Characterization of the inner disk around HD 141569 A from Keck/NIRC2 L-band vortex coronagraphy
Dimitri Mawet, Élodie Choquet, Olivier Absil +22
HD 141569 A is a pre-main sequence B9.5 Ve star surrounded by a prominent and complex circumstellar disk, likely still in a transition stage from protoplanetary to debris disk phas…
Very Low Mass Stellar and Substellar Companions to Solar-like Stars From MARVELS IV: A Candidate Brown Dwarf or Low-Mass Stellar Companion to HIP 67526
Peng Jiang, Jian Ge, Phillip Cargile +50
We report the discovery of a candidate brown dwarf or a very low mass stellar companion (MARVELS-5b) to the star HIP 67526 from the Multi-object APO Radial Velocity Exoplanet Large…
A Cautionary Tale: MARVELS Brown Dwarf Candidate Reveals Itself To Be A Very Long Period, Highly Eccentric Spectroscopic Stellar Binary
Claude E. Mack, Jian Ge, Rohit Deshpande +42
We report the discovery of a highly eccentric, double-lined spectroscopic binary star system (TYC 3010-1494-1), comprising two solar-type stars that we had initially identified as…
Very Low-mass Stellar and Substellar Companions to Solar-like Stars from Marvels III: A Short-Period Brown Dwarf Candidate Around An Active G0Iv Subgiant
Bo Ma, Jian Ge, Rory Barnes +45
We present an eccentric, short-period brown dwarf candidate orbiting the active, slightly evolved subgiant star TYC 2087-00255-1, which has effective temperature T_eff = 5903+/-42…
