Near-IR spectroscopy of asteroids 21 Lutetia, 89 Julia, 140 Siwa, 2181 Fogelin, and 5480 (1989YK8), potential targets for the Rosetta mission; remote observations campaign on IRTF
Mirel Birlan, Schelte J. Bus, Irina Belskaya +5
In the frame of the international campaign to observe potential target asteroids for the Rosetta mission, remote observations have been carried out between Observatoire de Paris, i…
Paschen beta emission as a tracer of outflow activity from T-Tauri stars, as compared to Optical Forbidden emission
E. T. Whelan, T. P. Ray, C. J. Davis
The Paschen beta (1.2822 micron) emission line found in the near-infrared spectra of T-Tauri stars (TTSs) is believed to trace the accretion of material onto the central star. We p…
A Disk Shadow Around the Young Star ASR 41 in NGC 1333
Klaus W. Hodapp, Christina H. Walker, Bo Reipurth +4
We present images of the young stellar object ASR 41 in the NGC 1333 star forming region at the wavelengths of H_alpha and [SII] and in the I, J, H, and K-bands. ASR 41 has the nea…
Detection of a warm molecular wind in DG Tauri
M. Takami, A. Chrysostomou, T. P. Ray +5
We detect near-infrared H2 emission in DG Tau using the Infrared Camera and Spectrograph (IRCS) on the 8.2-m SUBARU telescope. The spectra obtained along the jet axis show that the…
A survey of SiO 5-4 emission towards outflows from low-luminosity protostellar candidates
Andy G. Gibb, John S. Richer, Claire J. Chandler +1
We have observed the SiO J=5--4 line towards a sample of 25 low-luminosity (L* < 10^3 Lsun) protostellar outflow systems. The line was detected towards 7 of the 25 sources, a detec…
Far-infrared photometry of deeply embedded outflow sources
D. Froebrich, M. D. Smith, K. W. Hodapp +1
We present far-infrared maps and spectroscopy for a number of deeply embedded protostellar objects (CepE, HH211-MM, IC1396W, L1157, L1211, and RNO15FIR) from data that we acquired…
The Ghosts of Galaxies: Tidal Debris in Clusters
Michael D. Gregg, Michael J. West
Gravitational interactions in rich clusters can strip material from the outer parts of galaxies or even completely disrupt entire systems, giving rise to large scale, low surface b…
A Low Frequency Survey of the Galactic Plane Near l=11 degrees: Discovery of Three New Supernova Remnants
C. L. Brogan, K. E. Devine, T. J. Lazio +5
We have imaged a 1 deg^2 field centered on the known Galactic supernova remnant (SNR) G11.2-0.3 at 74, 330, and 1465 MHz with the Very Large Array radio telescope (VLA) and 235 MHz…
Hubble Space Telescope Observations of cD Galaxies and their Globular Cluster Systems
Andres Jordan, Patrick Cote, Michael J. West +3
We have used WFPC2 on the Hubble Space Telescope to obtain F450W and F814W images of four cD galaxies (NGC 541 in Abell 194, NGC 2832 in Abell 779, NGC 4839 in Abell 1656 and NGC 7…
A Ring Shaped Embedded Young Stellar (Proto)Cluster
M. S. Nanda Kumar, D. K. Ojha, C. J. Davis
We present sub-arcsec (FWHM ~ 0.5") J, H, K and L' images of a young stellar cluster associated with a candidate massive protostar IRAS22134+5834. The observations reveal a central…
L' and M' Standard Stars for the Mauna Kea Observatories Near-Infrared System
S. K. Leggett, T. G. Hawarden, M. J. Currie +7
We present L'and M' photometry, obtained at UKIRT using the Mauna Kea Observatories Near-IR filter set, for 46 and 31 standard stars, respectively. The L' standards include 25 from…
A search for the optical and near-infrared counterpart of the accreting millisecond X-ray pulsar XTE J1751-305
P. G. Jonker, G. Nelemans, Z. Wang +14
We have obtained optical and near-infrared images of the field of the accreting millisecond X-ray pulsar XTE J1751-305. There are no stars in the 0.7'' error circle (0.7'' is the o…
Penetration at high-z of the Greenberg "yellow stuff": Eyes to the Future with NGST
David L. Block, Ivanio Puerari, Marianne Takamiya +1
Quantitative morphological dust-penetrated templates for galaxies in our Local Universe may also serve as excellent templates for galaxies at high-z, because of partial/total decou…
An Optical and Near Infrared Search for Brown Dwarfs in the Pleiades Cluster
C. Nagashima, P. D. Dobbie, T. Nagayama +9
We have carried out a brown dwarf search over an area of 14' x 23' near the central portion of the Pleiades open cluster in five optical and near infrared bands (i', Z, J, H, Ks) w…
Carbon Monoxide Depletion in Orion B Molecular Cloud Cores
D. Savva, L. T. Little, R. R. Phillips +1
We have observed several cloud cores in the Orion B (L1630) molecular cloud in the 2-1 transitions of C18O, C17O and 13C18O. We use these data to show that a model where the cores…
