We review recent works on the dynamics of circumbinary accretion, including time variability,
angular momentum transfer between the disk and the binary, and the secular evolution of …

As planets form and grow within gaseous protoplanetary disks, the mutual gravitational
interaction between the disk and planet leads to the exchange of angular momentum and …

Circumstellar disks are thought to experience a rapid" transition" phase in their evolution that
can have a considerable impact on the formation and early development of planetary …

Photoionization heating from ultraviolet (UV) radiation incidents on the atmospheres of hot
Jupiters may drive planetary mass loss. Observations of stellar Lyman-α (Lyα) absorption …

We present the results of a high angular resolution (0 farcs 3≈ 40 AU) Submillimeter Array
survey of the 345 GHz (870 μm) thermal continuum emission from nine of the brightest, and …

Aims. We study the dependence of protoplanetary disk evolution on stellar mass using a
large sample of young stellar objects in nearby young star-forming regions. Methods. We …

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 …

Characterizing the atmospheres of extrasolar planets is the new frontier in exoplanetary
science. The last two decades of exoplanet discoveries have revealed that exoplanets are …

A primary goal of exoplanet characterization is to use a planet's current composition to
understand how that planet formed. For example, the C/O ratio has long been recognized as …

With a mass in the Neptune regime and a radius of Jupiter, WASP-107b presents a
challenge to planet formation theories. Meanwhile, the planet's low surface gravity and the …
