Imaging Cool Giant Planets in Reflected Light: Science Investigations and Synergy with Habitable Planets
Mark Marley, Nikole Lewis, Giada Arney +38
Planned astronomical observatories of the 2020s will be capable of obtaining reflected light photometry and spectroscopy of cool extrasolar giant planets. Here we explain that such…
HD 206893 B at High Spectral Resolution with the Keck Planet Imager and Characterizer (KPIC)
Ben Sappey, Quinn Konopacky, Clarissa R. Do O +38
We present an atmospheric characterization and orbital analysis of HD 206893 B, an exceptionally red, L/T-transition substellar companion in a multiplanetary system, via Keck Plane…
Differentiating Formation Models with New Dynamical Masses for the PDS 70 Protoplanets
David Trevascus, Sarah Blunt, Valentin Christiaens +22
Hot- and cold-start planet formation models predict differing luminosities for the young, bright planets that direct imaging surveys are most sensitive to. However, precise mass es…
CO and potential variability in Pictoris b with GRAVITY+
Antonia von Stauffenberg, Jonas Sauter, Paul Mollière +18
The CO/CO ratio was introduced as an indicator for where in the disk a planet has formed. Previously a lower value compared to the host star's was suggested to show t…
Status of the Keck Planet Imager and Characterizer Phase II Development
Jacklyn Pezzato, Nemanja Jovanovic, Dimitri Mawet +15
The Keck Planet Imager and Characterizer comprises of a series of upgrades to the Keck II adaptive optics system and instrument suite to improve the direct imaging and high resolut…
A Clear View of a Cloudy Brown Dwarf Companion from High-Resolution Spectroscopy
Jerry W. Xuan, Jason Wang, Jean-Baptiste Ruffio +37
Direct imaging studies have mainly used low-resolution spectroscopy () to study the atmospheres of giant exoplanets and brown dwarf companions, but the presence of clo…
