Inferring Magnetic Field Morphology and Dust Scattering Geometry from Mid-IR Polarimetry: the Extended Aitken Method
Frank Városi, Charles M. Telesco, Christopher M. Wright +1
The Aitken method is a useful approach for decomposing mid-IR polarimetry of silicates in astronomical sources into emissive and absorptive components. Here we extend this method t…
GTC/CanariCam Mid-IR Polarimetry of Magnetic Fields in Star-Forming Region W51 IRS2
Charles M. Telesco, Han Zhang, Frank Varosi +4
We present 0.4 arcsec-resolution imaging polarimetry at 8.7, 10.3, and 12.5 microns, obtained with CanariCam at the Gran Telescopio Canarias, of the central region of W51 IRS2. The…
Mid-Infrared Polarization of the Diffuse Interstellar Medium toward CygOB2-12
Charles M. Telesco, Frank Varosi, Christopher Wright +3
We present the first mid-IR detection of the linear polarization toward the star CygOB2-12, a luminous blue hypergiant that, with Av of ~10 mag of foreground extinction, is a bench…
On the Diagnostic Power of FIR/Sub-mm SED Fitting in Massive Galactic Molecular Clumps
Rebecca L. Pitts, Peter J. Barnes, Frank Varosi
We used FIR and submillimeter continuum data from Herschel and the Atacama Pathfinder EXperiment (APEX) to fit pixel-by-pixel modified Planck SEDs to prestellar and protostellar cl…
The first super-Earth Detection from the High Cadence and High Radial Velocity Precision Dharma Planet Survey
Bo Ma, Jian Ge, Matthew Muterspaugh +23
The Dharma Planet Survey (DPS) aims to monitor about 150 nearby very bright FGKM dwarfs (within 50 pc) during 20162020 for low-mass planet detection and characterization using t…
CIRCE: The Canarias InfraRed Camera Experiment for the Gran Telescopio Canarias
Stephen S. Eikenberry, Miguel Charcos, Michelle L. Edwards +51
The Canarias InfraRed Camera Experiment (CIRCE) is a near-infrared (1-2.5 micron) imager, polarimeter and low-resolution spectrograph operating as a visitor instrument for the Gran…
Exploring the Brown Dwarf Desert: New Substellar Companions from the SDSS-III MARVELS Survey
Nolan Grieves, Jian Ge, Neil Thomas +27
Planet searches using the radial velocity technique show a paucity of companions to solar-type stars within ~5 AU in the mass range of ~10 - 80 M. This deficit, know…
MARVELS-1b: A Short-Period, Brown Dwarf Desert Candidate from the SDSS-III MARVELS Planet Search
Brian L. Lee, Jian Ge, Scott W. Fleming +59
We present a new short-period brown dwarf candidate around the star TYC 1240-00945-1. This candidate was discovered in the first year of the Multi-object APO Radial Velocity Exopla…
Radiative Transfer in Clumpy and Fractal Media
Frank Varosi, Eli Dwek
A Monte Carlo model of radiative transfer in multi-phase dusty media is applied to the situation of stars and clumpy dust in a sphere or a disk. The distribution of escaping and ab…
Analytical Approximations for Calculating the Escape and Absorption of Radiation in Clumpy Dusty Environments
Frank Varosi, Eli Dwek
We present analytical approximations for calculating the scattering, absorption and escape of nonionizing photons from a spherically symmetric two-phase clumpy medium, with either…
Survey of Fine-Scale Structure in the Far-Infrared Milky Way
William H. Waller, Frank Varosi, Francois Boulanger +1
Using the IRAS Infrared Sky Survey Atlas, we have made 60 x 60 deg mosaics of the far-infrared emission in the Milky Way. By applying a median normalizing spatial filter, we were a…
