Medium-separation binaries do not affect the first steps of planet formation
I. Pascucci, D. Apai, E. E. Hardegree-Ullman +3
The first steps of planet formation are marked by the growth and crystallization of sub-micrometer-sized dust grains accompanied by dust settling toward the disk midplane. In this…
A Survey for Massive Giant Planets in Debris Disks with Evacuated Inner Cavities
D. Apai, M. Janson, A. Moro-Martin +9
The commonality of collisionally replenished debris around main sequence stars suggests that minor bodies are frequent around Sun-like stars. Whether or not debris disks in general…
Dust rings and filaments around the isolated young star V1331 Cygni
Sascha P. Quanz, Daniel Apai, Thomas Henning
We characterize the small and large scale environment of the young star V1331 Cygni with high resolution HST/WFPC2 and Digitized Sky Survey images. In addition to a previously know…
Nearby debris disk systems with high fractional luminosity reconsidered
A. Moor, P. Abraham, A. Derekas +5
By searching the IRAS and ISO databases we compiled a list of 60 debris disks which exhibit the highest fractional luminosity values (fd>10^-4) in the vicinity of the Sun (d<120pc)…
HST/NICMOS observations of a proto-brown dwarf candidate
D. Apai, L. V. Toth, Th. Henning +3
We present deep HST/NICMOS observations peering through the outflow cavity of the protostellar candidate IRAS 04381+2540 in the Taurus Molecular Cloud-1. A young stellar object as…
Grain growth and dust settling in a brown dwarf disk: Gemini/T-ReCS observations of CFHT-BD-Tau 4
D. Apai, I. Pascucci, M. F. Sterzik +4
We present accurate mid-infrared observations of the disk around the young, bona-fide brown dwarf CFHT-BD-Tau 4. We report GEMINI/T-ReCS measurements in the 7.9, 10.4 and 12.3 micr…
