RV measurements of directly imaged brown dwarf GQ Lup B to search for exo-satellites
Katelyn Horstman, Jean-Baptiste Ruffio, Konstantin Batygin +35
GQ Lup B is one of the few substellar companions with a detected cicumplanetary disk, or CPD. Observations of the CPD suggest the presence of a cavity, possibly formed by an exo-sa…
Deepest limits on scattered light emission from the Epsilon Eridani inner debris disk with HST/STIS
Sai Krishanth P. M., Ewan S. Douglas, Ramya M. Anche +9
Epsilon Eridani ( Eri) is one of the first debris disk systems detected by the Infrared Astronomical Satellite (IRAS). However, the system has thus far eluded detection in scatt…
The high-contrast performance of the Keck Planet Imager and Characterizer
Jason J. Wang, Dimitri Mawet, Jerry W. Xuan +25
The Keck Planet Imager and Characterizer (KPIC), a series of upgrades to the Keck II Adaptive Optics System and Instrument Suite, aims to demonstrate high-resolution spectroscopy o…
Rotation and Abundances of the Benchmark Brown Dwarf HD 33632 Ab from Keck/KPIC High-resolution Spectroscopy
Chih-Chun Hsu, Jason J. Wang, Jerry W. Xuan +24
We present the projected rotational velocity and molecular abundances for HD 33632 Ab obtained via Keck Planet Imager and Characterizer high-resolution spectroscopy. HD 33632 Ab is…
Keck Primary Mirror Closed-Loop Segment Control using a Vector-Zernike Wavefront Sensor
Maissa Salama, Charlotte Guthery, Vincent Chambouleyron +17
We present the first on-sky segmented primary mirror closed-loop piston control using a Zernike wavefront sensor (ZWFS) installed on the Keck II telescope. Segment co-phasing error…
Vortex Fiber Nulling for Exoplanet Observations: First Direct Detection of M Dwarf Companions around HIP 21543, HIP 94666, and HIP 50319
Daniel Echeverri, Jerry W. Xuan, John D. Monnier +35
Vortex fiber nulling (VFN) is a technique for detecting and characterizing faint companions at small separations from their host star. A near-infrared (m) VFN demonstrat…
