Characterizing Microlensing Planetary System OGLE-2014-BLG-0676L with High-Resolution Image Constrained Light Curve Modeling
Asahi Idei, Naoki Koshimoto, Daisuke Suzuki +12
We present an analysis that incorporates high-resolution Keck adaptive optics (AO) imaging into microlensing light-curve modeling for the planetary microlensing event OGLE-2014-BLG…
Resolving protoplanetary H-alpha emission with the high-resolution spectrograph RISTRETTO
J. W. Blackman, C. Mordasini, G. -D. Marleau +4
Thousands of exoplanets have been discovered to date, but only a handful of them are young planets in the latter stages of their formation. H-alpha emission is a strong tracer of t…
Super-Earth masses and stellar abundances from NIRPS reveal tentative evidence for water-rich formation around M dwarfs
Drew Weisserman, Nicole Gromek, Ryan Cloutier +98
Tracing the compositional link between terrestrial super-Earths and their host stars provides clues to their dominant formation pathway. By constraining the stellar abundances of r…
MOA-2010-BLG-328: Keck and HST Expose the Limits of Occams Razor in Microlensing
Aikaterini Vandorou, David P. Bennett, Jean-Philippe Beaulieu +7
We present high resolution follow-up data of the planetary microlensing event MOA-2010-BLG-328, using Keck and the Hubble. Keck data, taken 8 years after the event, reveal a strong…
OGLE-2016-BLG-1195Lb: A Sub-Neptune Beyond the Snow Line of an M-dwarf Confirmed by Keck AO
Aikaterini Vandorou, Lisa Dang, David P. Bennett +12
We present the analysis of high resolution follow-up observations of OGLE-2016-BLG-1195 using Laser Guide Star Adaptive Optics with Keck, seven years after the event's peak. We res…
TASSIE: a TASmanian Search for Inclined Exoplanets
T. Plunkett, A. A. Cole, J. P. Beaulieu +5
We present the first results of a pilot 'TASmanian Search for Inclined Exoplanets' (TASSIE) program. This includes observations and analysis of five short-period exoplanet candidat…
