The Debris Disk Explorer: a balloon-borne coronagraph for observing debris disks
Lewis C. Roberts, Geoffrey Bryden, Wesley Traub +9
The Debris Disk Explorer (DDX) is a proposed balloon-borne investigation of debris disks around nearby stars. Debris disks are analogs of the Asteroid Belt (mainly rocky) and Kuipe…
Herschel's "Cold Debris Disks": Background Galaxies or Quiescent Rims of Planetary Systems?
A. V. Krivov, C. Eiroa, T. Löhne +24
(abridged) Infrared excesses associated with debris disk host stars detected so far peak at wavelengths around ~100μm or shorter. However, six out of 31 excess sources in the Hersc…
WFIRST-2.4: What Every Astronomer Should Know
D. Spergel, N. Gehrels, J. Breckinridge +43
The Astro2010 Decadal Survey recommended a Wide Field Infrared Survey Telescope (WFIRST) as its top priority for a new large space mission. The report of the WFIRST-AFTA Science De…
DUst Around NEarby Stars. The survey observational results
C. Eiroa, J. P. Marshall, A. Mora +47
Debris discs are a consequence of the planet formation process and constitute the fingerprints of planetesimal systems. Their solar system's counterparts are the asteroid and Edgew…
Vertical settling and radial segregation of large dust grains in the circumstellar disk of the Butterfly Star
Christian Gräfe, Sebastian Wolf, Stephane Guilloteau +4
Context: Circumstellar disks are considered to be the environment for the formation of planets. The growth of dust grains in these disks is the first step in the core accretion-gas…
Asteroid Belts in Debris Disk Twins: VEGA and FOMALHAUT
Kate Y. L. Su, G. H. Rieke, R. Malhotra +8
Vega and Fomalhaut, are similar in terms of mass, ages, and global debris disk properties; therefore, they are often referred as "debris disk twins". We present Spitzer 10-35 um sp…
