Optical Images of an Exosolar Planet 25 Light Years from Earth
Paul Kalas, James R. Graham, Eugene Chiang +6
Fomalhaut is a bright star 7.7 parsecs (25 light years) from Earth that harbors a belt of cold dust with a structure consistent with gravitational sculpting by an orbiting planet.…
Fomalhaut's Debris Disk and Planet: Constraining the Mass of Fomalhaut b From Disk Morphology
E. Chiang, E. Kite, P. Kalas +2
Following the optical imaging of the exoplanet candidate Fomalhaut b (Fom b), we present a numerical model of how Fomalhaut's debris disk is gravitationally shaped by an interior p…
New Circumstellar Dust Creation in V838 Monocerotis
John P. Wisniewski, Mark Clampin, Karen S. Bjorkman +2
We report high spatial resolution 11.2 and 18.1 micron imaging of the eruptive variable V838 Monocerotis, obtained with Gemini Observatory's Michelle in 2007 March. The 2007 flux d…
The HD 163296 Circumstellar Disk in Scattered Light: Evidence of Time-Variable Self-Shadowing
John P. Wisniewski, Mark Clampin, Carol A. Grady +6
We present the first multi-color view of the scattered light disk of the Herbig Ae star HD 163296, based on coronagraphic observations from the Hubble Space Telescope Advanced Came…
High Spatial Resolution Mid-IR Imaging of V838 Monocerotis: Evidence of New Circumstellar Dust Creation
John P. Wisniewski, Mark Clampin, Karen S. Bjorkman +1
We report high spatial resolution 11.2 and 18.1 micron imaging of V838 Monocerotis obtained with Gemini Observatory's Michelle instrument in 2007 March. Strong emission is observed…
