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…
A Ring of Warm Dust in the HD 32297 Debris Disk
Michael P. Fitzgerald, Paul G. Kalas, James R. Graham
We report the detection of a ring of warm dust in the edge-on disk surrounding HD 32297 with the Gemini-N/MICHELLE mid-infrared imager. Our N'-band image shows elongated structure…
Evidence for a Long-Standing Top-Heavy IMF in the Central Parsec of the Galaxy
H. Maness, F. Martins, S. Trippe +10
We classify 329 late-type giants within 1 parsec of Sgr A*, using the adaptive optics integral field spectrometer SINFONI on the VLT. These observations represent the deepest spect…
Stellar and Molecular Radii of a Mira Star: First Observations with the Keck Interferometer Grism
J. A. Eisner, J. R. Graham, R. L. Akeson +6
Using a new grism at the Keck Interferometer, we obtained spectrally dispersed (R ~ 230) interferometric measurements of the Mira star R Vir. These data show that the measured radi…
Speckle Statistics in Adaptively Corrected Images
Michael P. Fitzgerald, James R. Graham
(abridged) Imaging observations are generally affected by a fluctuating background of speckles, a particular problem when detecting faint stellar companions at small angular separa…
Mass Segregation and the Initial Mass Function of Super Star Cluster M82-F
Nate McCrady, James R. Graham, William D. Vacca
We investigate the Initial Mass Function and mass segregation in super star cluster M82-F with high resolution Keck/NIRSPEC echelle spectroscopy. Cross-correlation with template su…
