How do Most Planets Form? -- Constraints on Disk Instability from Direct Imaging
Markus Janson, Mariangela Bonavita, Hubert Klahr +1
Core accretion and disk instability have traditionally been regarded as the two competing possible paths of planet formation. In recent years, evidence have accumulated in favor of…
Discovery of two L & T binaries with wide separations and peculiar photometric properties
Étienne Artigau, David Lafrenière, René Doyon +6
We present spatially resolved photometric and spectroscopic observations of two wide brown dwarf binaries uncovered by the SIMP near-infrared proper motion survey. The first pair (…
High-contrast Imaging Search for Planets and Brown Dwarfs around the Most Massive Stars in the Solar Neighborhood
Markus Janson, Mariangela Bonavita, Hubert Klahr +3
There has been a long-standing discussion in the literature as to whether core accretion or disk instability is the dominant mode of planet formation. Over the last decade, several…
Discovery of a ~23 Mjup Brown Dwarf Orbiting ~700 AU from the Massive Star HIP 78530 in Upper Scorpius
David Lafrenière, Ray Jayawardhana, Markus Janson +3
We present the discovery of a substellar companion on a wide orbit around the ~2.5 Msun star HIP 78530, which is a member of the 5 Myr-old Upper Scorpius association. We have obtai…
