Light Echoes of Time-resolved Flares and Application to Kepler Data

The Open Journal of Astrophysics
Light echoes of stellar flares provide an intriguing option for exploring protoplanetary disks in young stellar systems. Previous work on light echoes of circumstellar disks made use of delta-function flares for modeling.

Cloud Dissipation and Disk Wind in the Late Phase of Star Formation

The Astrophysical Journal
We perform a long-term simulation of star and disk formation using three-dimensional nonideal magnetohydrodynamics. The simulation starts from a prestellar cloud and proceeds through the long-term evolution of the circumstellar disk until ∼1.5 × 10 ^5 yr

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 ...

Identification of Possible Stellar Companions via Speckle Interferometry in a Sample of Be Stars II

The Astronomical Journal
This study investigates the identification of possible stellar companions in a sample of Be stars using speckle interferometry. Be stars, which are rapidly rotating B-type stars exhibiting emission lines due to the presence of circumstellar disks, have ...
