The Hawaii Infrared Parallax Program. VI. The fundamental properties of 1000+ ultracool dwarfs and planetary-mass objects using optical to mid-infrared spectral …
We derive the bolometric luminosities (L bol) of 865 field-age and 189 young ultracool
dwarfs (spectral types M6–T9, including 40 new discoveries presented here) by directly …

Detecting exomoons from radial velocity measurements of self-luminous planets: application to observations of HR 7672 B and future prospects
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 elusive objects …

Assessing the C/O Ratio Formation Diagnostic: A Potential Trend with Companion Mass
The carbon-to-oxygen (C/O) ratio in an exoplanet atmosphere has been suggested as a
potential diagnostic of planet formation. Now that a number of exoplanets have measured …
