Spectropolarimetry and the Study of Circumstellar Disks [PDF]

, 2007
Circumstellar disks play an important role in many stages of the evolution of stars. However, it is only possible to directly image circumstellar disks for a few of the nearest stars. For massive stars, the situation is even more difficult, as they are on average further away than the more numerous low mass stars.

Betelgeuse: Detection of the Expanding Wake of the Companion Star

The Astrophysical Journal
Recent analyses conclude that Betelgeuse, a red supergiant star (HD 39801), likely has a companion object with a period of ∼2000 days orbiting at only 2.3 R _⋆ , deep in the chromosphere of the supergiant.

Thermal Structure and Millimeter Emission from a Protoplanetary Disk with Embedded Protoplanets from Radiative Transfer Modeling

The Astrophysical Journal
The discovery of protoplanets and circumplanetary disks provides a unique opportunity to characterize planet formation through observations. Massive protoplanets shape the physical and chemical structure of their host circumstellar disk by accretion ...
