Circumstellar Disks
Steven V. W. Beckwith
This article is a tutorial on deriving physical properties from the spectral energy distributions of circumstellar disks. It includes a new derivation of disk mass from millimeter-…
Dust Properties and Assembly of Large Particles in Protoplanetary Disks
Steven V. W. Beckwith, Thomas Henning, Yoshitsugu Nakagawa
Recent research on the buildup of rocks from small dust grains has reaffirmed that grain growth in protoplanetary disks should occur quickly. Calculation of growth rates have been…
Circumstellar Disks Around Pre-Main-Sequence Stars: What ISO Can Tell Us
A. Natta, M. R. Meyer, S. V. W. Beckwith
ISO observations will improve our understanding of disks around low-mass pre-main-sequence stars in various ways. In particular, ISO can measure simultaneously spectral energy dist…
Consequences of a Non-Detection of Forming Galaxies by an Infrared Survey
F. Mannucci, D. Thompson, S. V. W. Beckwith
We present the results of a narrowband search for forming galaxies at high redshifts. Given the coverage of 276 square minutes of arc, this is the most extended search for extragal…
