Evidence of a Low-Energy Cutoff in the Injected Spectrum of a Pulsar Wind Nebula
Zhihong Shi, C. -Y. Ng, Niccol`o Bucciantini +5
Bow-shock pulsar wind nebulae (PWNe) are synchrotron sources formed when the outflow of supersonic pulsars is confined by the surrounding interstellar medium. These sources are dom…
An Empirical Planetesimal Belt Radius - Stellar Luminosity Relation
L. Matrà, S. Marino, G. M. Kennedy +3
Resolved observations of millimetre-sized dust, tracing larger planetesimals, have pinpointed the location of 26 Edgeworth-Kuiper belt analogs. We report that a belt's distance …
The Multiple Young Stellar Objects of HBC 515: An X-ray and Millimeter-wave Imaging Study in (Pre-main Sequence) Diversity
D. A. Principe, G. G. Sacco, J. H. Kastner +3
We present Chandra X-ray Observatory and Submillimeter Array (SMA) imaging of HBC 515, a system consisting of multiple young stellar objects (YSOs). The five members of HBC 515 rep…
ALMA Observations of HD141569's Circumstellar Disk
J. A. White, A. C. Boley, A. M. Hughes +5
We present ALMA band 7 (345 GHz) continuum and CO(J = 3-2) observations of the circumstellar disk surrounding HD141569. At an age of about 5 Myr, the disk has a complex morp…
Steepening of the 820 micron continuum surface-brightness profile signals dust evolution in TW Hya's disk
Michiel R. Hogerheijde, David Bekkers, Paola Pinilla +5
Grain growth in planet-forming disks is the first step toward the formation of planets. The growth of grains and their inward drift leaves a distinct imprint on the dust surface-de…
On the structure of the transition disk around TW Hya
J. Menu, R. van Boekel, T. Henning +25
For over a decade, the structure of the inner cavity in the transition disk of TW Hydrae has been a subject of debate. Modeling the disk with data obtained at different wavelengths…
Matryoshka Holes: Nested Emission Rings in the Transitional Disk Oph IRS 48
Joanna M. Brown, Katherine A. Rosenfeld, Sean M. Andrews +2
The processes that form transition disks - disks with depleted inner regions - are not well understood; possible scenarios include planet formation, grain growth and photoevaporati…
Ionized Gas Kinematics and Morphology in Sgr B2 Main on 1000 AU Scales
Christopher G. De Pree, David J. Wilner, W. Miller Goss
We have imaged the Sgr B2 Main region with the Very Large Array in the BnA configuration ( = 0\farcs13) in both the H52 (45.453 GHz) radio recombination line (RRL) and…
New constraints on dust grain size and distribution in CQ Tau
A. Banzatti, L. Testi, A. Isella +3
Grain growth in circumstellar disks is expected to be the first step towards the formation of planetary systems. There is now evidence for grain growth in several disks around youn…
Exoplanet Characterization and the Search for Life
J. Kasting, W. Traub, A. Roberge +119
Over 300 extrasolar planets (exoplanets) have been detected orbiting nearby stars. We now hope to conduct a census of all planets around nearby stars and to characterize their atmo…
183 GHz HO maser emission around the low-mass protostar Serpens SMM1
T. A. van Kempen, D. Wilner, M. Gurwell
We report the first interferomteric detection of 183 GHz water emission in the low-mass protostar Serpens SMM1 using the Submillimeter Array with a resolution of 3 and rms of $\…
Evidence for dust clearing through resolved submillimeter imaging
J. M. Brown, G. A. Blake, C. Qi +3
Mid-infrared spectrophotometric observations have revealed a small sub-class of circumstellar disks with spectral energy distributions (SEDs) suggestive of large inner gaps with lo…
Resolving the molecular environment of Super Star Clusters in Henize 2-10
G. Santangelo, L. Testi, L. Gregorini +4
The rate of star formation both in the Galaxy and in external galaxies should be related to the physical properties of the molecular clouds from which stars form. This is expected…
Search for Molecular Gas in the quasar SDSS 1044-0125 at z=5.73
D. J. Wilner, M. C. H. Wright, J. Di Francesco
We report upper limits on CO J=2--1 and CO J=5--4 emission from the quasar SDSSp J104433.04-012502.2 at z=5.73 from observations made with the Berkeley-Illinois-Maryland-Associatio…
Constraints on properties of the protoplanetary disks around UX Ori and CQ Tau
L. Testi, A. Natta, D. S. Shepherd +1
We present Very Large Array observations of the intermediate mass pre-main-sequence stars UX Ori and CQ Tau at 7mm, 3.6cm, and 6cm. These stars are members of the UX Ori variabilit…
VLA Imaging of the Disk Surrounding the Nearby Young Star TW Hya
D. J. Wilner, P. T. P. Ho, J. H. Kastner +1
The TW Hya system is perhaps the closest analog to the early solar nebula. We have used the Very Large Array to image TW Hya at wavelengths of 7mm and 3.6 cm with resolutions 0.1 a…
Proposed identification of Hubble Deep Field submillimeter source HDF 850.1
D. Downes, R. Neri, A. Greve +23
The IRAM interferometer has been used to detect the submm source HDF 850.1 found by Hughes et al. (1998) in the Hubble Deep Field. The flux density measured at 1.3mm is 2.2 mJy, in…
Detection of CO(4-3), CO(9-8), and dust emission in the BAL quasar APM 08279+5255 at a redshift of 3.9
D. Downes, R. Neri, T. Wiklind +2
We detected with the IRAM interferometer the lines of CO(4-3) and CO(9-8) from the recently-discovered broad absorption line quasar APM 08279+5255. The molecular lines are at a red…
