Tracing large-scale structures in circumstellar disks with ALMA

, 2012
Planets are supposed to form in circumstellar disks. The gravitational potential of a planet perturbs the disk and leads to characteristic structures, i.e. spiral waves and gaps, in the disk's density profile.

HD101584: Circumstellar characteristics and evolutionary status

, 2019
We have performed a study of the characteristics of the circumstellar environment of the binary object HD101584, that provides information on a likely evolutionary scenario.

Probing Dust and Gas Properties Using Ringed Disks

The Astrophysical Journal Letters
How rapidly a planet grows in mass and how far it may park from the host star depend sensitively on two nondimensional parameters: Stokes number St and turbulent α .

The last gasps of VY CMa: Aperture synthesis and adaptive optics imagery

, 1998
We present new observations of the red supergiant VY CMa at 1.25 micron, 1.65 micron, 2.26 micron, 3.08 micron and 4.8 micron. Two complementary observational techniques were utilized: non-redundant aperture masking on the 10-m Keck-I telescope yielding ...

Deep Search for a Scattered Light Dust Halo Around Vega with the Hubble Space Telescope

The Astronomical Journal
We present a provisory scattered-light detection of the Vega debris disk using deep Hubble Space Telescope (HST) coronagraphy (PID 16666). At only 7.7 pc, Vega is immensely important in debris disk studies both for its prominence and also because it ...
