CHARIS and SPHERE/IFS infrared spectra of HIP 21152
Benchmark brown dwarf companions with well-determined ages and model- independent masses are powerful tools to test substellar evolutionary models and probe the formation of... -
Radial velocity and rotation period of HIP 33069b
We present the discovery and characterization of HIP33609b, a transiting warm brown dwarf orbiting a late B-star, discovered by NASA's Transiting Exoplanet Survey Satellite as... -
Polarization monitoring of 2MJ21392676+0220226
Recent atmospheric models for brown dwarfs suggest that the existence of clouds in substellar objects is not needed to reproduce their spectra, nor their rotationally induced... -
KPIC radial velocity follow up of HR 7672 B
The detection of satellites around extrasolar planets, so called exomoons, remains a largely unexplored territory. In this work, we study the potential of detecting these... -
Light curve of microlensing MOA-2019-BLG-008L
We report on the observations, analysis and interpretation of the microlensing event MOA-2019-BLG-008. The observed anomaly in the photometric light curve is best described... -
NIR light curve of 2MASS J00501994-3322402
Only a handful of late T brown dwarfs have been monitored for spectrophotometric variability, leaving incomplete the study of the atmospheric cloud structures of the coldest... -
NICMOS Kernel-phase Interferometry. I. Brown dwarfs
Filling out the dearth of detections between direct imaging and radial velocity surveys will test theories of planet formation and (sub)stellar binarity across the full range of... -
IR light curve of VHS1256-1257b in 2018 & 2020 epochs
The photometric and spectral variability of brown dwarfs probes heterogeneous temperature and cloud distributions and traces the atmospheric circulation patterns. We present a... -
The Perkins INfrared Exosatellite Survey. I.
We describe the Perkins INfrared Exosatellite Survey (PINES), a near-infrared photometric search for short-period transiting planets and moons around a sample of 393... -
Radial Velocities of TOI-811 and TOI-852
We report the discovery of two transiting brown dwarfs (BDs), TOI-811b and TOI-852b, from NASA's Transiting Exoplanet Survey Satellite mission. These two transiting BDs have... -
Volume-limited sample of cool dwarfs. I. L0-T8 dwarfs
We present a new volume-limited sample of L0-T8 dwarfs out to 25pc defined entirely by parallaxes, using our recent measurements from UKIRT/WFCAM along with Gaia DR2 and... -
Photometry of 38708 stars in W3 complex with HST
We have used archival infrared images obtained with the Wide Field Camera 3 on board the Hubble Space Telescope to constrain the initial mass function of low-mass stars and... -
IR spectra of 5 brown dwarfs with Gemini North IRS
Cold brown dwarfs are excellent analogs of widely separated, gas giant exoplanets, and provide insight into the potential atmospheric chemistry and physics we may encounter in... -
Upper Scorpius spectroscopy and photometry
We have refined the census of stars and brown dwarfs in the Upper Sco association (~10Myr, ~145pc) by (1) updating the selection of candidate members from our previous survey to... -
Spitzer variability detections of 79 brown dwarfs
We present Spitzer Space Telescope variability monitoring observations of three low-gravity L dwarfs with previous detections of variability in the near-IR: 2MASSJ0045+16,... -
OSIRIS K-band spectroscopy of {kappa} Andromedae b
We present moderate-resolution (R~4000) K-band spectra of the "super- Jupiter," {kappa}-Andromedae-b. The data were taken with the OSIRIS integral field spectrograph at Keck... -
Spectroscopic transit depths of LHS 3844b
Atmospheric studies of spectroscopically accessible terrestrial exoplanets lay the groundwork for comparative planetology between these worlds and the solar system terrestrial... -
Gaia survey of stars associated with Lupus Clouds
I have used high-precision photometry and astrometry from the second data release of the Gaia mission to perform a survey for young stars associated with the Lupus clouds, which... -
New AO obs. of exoplanets & brown dwarf companions
The orbital eccentricities of directly imaged exoplanets and brown dwarf companions provide clues about their formation and dynamical histories. We combine new high-contrast... -
Hawaii IR parallax program. IV. L0-T8 BDs with UKIRT
We present parallaxes, proper motions, and J-band photometry for 348 L and T dwarfs measured using the wide-field near-infrared camera (WFCAM) on the United Kingdom Infrared...
