Chasing Shadows: Rotation of the Azimuthal Asymmetry in the TW Hya Disk
John H. Debes, Charles A. Poteet, Hannah Jang-Condell +8
We have obtained new images of the protoplanetary disk orbiting TW Hya in visible, total intensity light with the Space Telescope Imaging Spectrograph (STIS) on the Hubble Space Te…
Peering into the Giant Planet Forming Region of the TW Hydrae Disk with the Gemini Planet Imager
Valerie A. Rapson, Joel H. Kastner, Maxwell A. Millar-Blanchaer +1
We present Gemini Planet Imager (GPI) adaptive optics near-infrared images of the giant planet-forming regions of the protoplanetary disk orbiting the nearby (D = 54 pc), pre-main…
Scattered Light from Dust in the Cavity of the V4046 Sgr Transition Disk
Valerie A. Rapson, Joel H. Kastner, Sean M. Andrews +4
We report the presence of scattered light from dust grains located in the giant planet formation region of the circumbinary disk orbiting the ~20-Myr-old close (~0.045 AU separatio…
V4046 Sgr: Touchstone to Investigate Spectral Type Discrepancies for Pre-main Sequence Stars
Joel H. Kastner, Valerie Rapson, Benjamin Sargent +2
Determinations of the fundamental properties (e.g., masses and ages) of late-type, pre-main sequence (pre-MS) stars are complicated by the potential for significant discrepancies b…
A Spitzer View of Mon OB1 East/NGC 2264
Valerie A. Rapson, Judith L. Pipher, Robert A. Gutermuth +4
We present Spitzer 3.6, 4.5, 5.8, 8.0, and 24 micron images of the Mon OB1 East giant molecular cloud, which contains the young star forming region NGC 2264, as well as more extend…
The Chandra X-ray Survey of Planetary Nebulae (ChanPlaNS): Probing Binarity, Magnetic Fields, and Wind Collisions
J. H. Kastner, R. Montez, B. Balick +23
We present an overview of the initial results from the Chandra Planetary Nebula Survey (ChanPlaNS), the first systematic (volume-limited) Chandra X-ray Observatory survey of planet…
A Spitzer IRS Survey of NGC 1333: Insights into disk evolution from a very young cluster
L. A. Arnold, Dan M. Watson, K. H. Kim +11
We report on the λ = 5-36μm Spitzer Infrared Spectrograph spectra of 79 young stellar objects in the very young nearby cluster NGC 1333. NGC 1333's youth enables the study of early…
