PLANET FORMATION AROUND STARS OF VARIOUS MASSES : THE SNOW LINE AND THE FREQUENCY OF GIANT PLANETS
We use a semianalytic circumstellar disk model that considers movement of the snow line through evolution of accretion and the central star to investigate how gas giant frequency changes with stellarExpand

Resolved debris discs around A stars in the Herschel DEBRIS survey
The majority of debris discs discovered so far have only been detected through infrared excess emission above stellar photospheres. While disc properties can be inferred from unresolved photometryExpand

Planet Formation around Stars of Various Masses: Hot Super-Earths
We consider trends resulting from two formation mechanisms for short-period super-Earths: planet-planet scattering and migration. We model scenarios where these planets originate near the snow lineExpand

TOWARD CHEMICAL CONSTRAINTS ON HOT JUPITER MIGRATION
The origin of hot Jupiters—gas giant exoplanets orbiting very close to their host stars—is a long-standing puzzle. Planet formation theories suggest that such planets are unlikely to have formed inExpand

YOUNG “DIPPER” STARS IN UPPER SCO AND OPH OBSERVED BY K2
We present ten young ($\lesssim$10 Myr) late-K and M dwarf stars observed in K2 Campaign 2 that host protoplanetary disks and exhibit quasi-periodic or aperiodic dimming events. Their optical lightExpand

MILLIMETER EMISSION STRUCTURE IN THE FIRST ALMA IMAGE OF THE AU Mic DEBRIS DISK
We present 1.3 mm ALMA Cycle 0 observations of the edge-on debris disk around the nearby, similar to 10 Myr old, M-type star AU Mic. These observations obtain 0 ''.6 (6 AU) resolution and reveal twoExpand

Collisional evolution of irregular satellite swarms: detectable dust around Solar system and extrasolar planets
Since the 1980s it has been becoming increasingly clear that the Solar system’s irregular satellites are collisionally evolved. The current populations are remnants of much more massive swarms thatExpand

Confusion limited surveys: using WISE to quantify the rarity of warm dust around Kepler stars
We describe a search for infra-red excess emission from dusty circumstellar material around 180,000 stars observed by the Kepler and WISE missions. This study is motivated by i) the potential to findExpand
