The Arizona Radio Observatory CO Mapping Survey of Galactic Molecular Clouds: III. The Serpens Cloud in CO J=2-1 and 13CO J=2-1 Emission
K. J. Burleigh, J. H. Bieging, A. Chromey +2
We mapped 12CO and 13CO J = 2-1 emission over 1.04 square deg of the Serpens molecular cloud with 38 arcsec spatial and 0.3 km/s spectral resolution using the Arizona Radio Observa…
Sub-millimeter observations of IRAS and WISE debris disk candidates
J. Bulger, T. Hufford, A. Schneider +7
A set of six debris disk candidates identified with IRAS or WISE excesses were observed at either 350 um or 450 um with the CSO. Five of the targets - HIP 51658, HIP 68160, HIP 735…
Optical and Infrared Photometry of the Type Ia Supernovae 1991T, 1991bg, 1999ek, 2001bt, 2001cn, 2001cz, and 2002bo
Kevin Krisciunas, Nicholas B. Suntzeff, Mark M. Phillips +28
We present optical and/or infrared photometry of the Type Ia supernovae SN 1991T, SN 1991bg, SN 1999ek, SN 2001bt, SN 2001cn, SN 2001cz, and SN 2002bo. All but one of these superno…
Deep Near-Infrared Observations of L1014: Revealing the nature of the core and its embedded source
T. L. Huard, P. C. Myers, D. C. Murphy +7
Recently, the Spitzer Space Telescope discovered L1014-IRS, a mid-infrared source with protostellar colors, toward the heretofore "starless" core L1014. We present deep near-infrar…
Time-Variable Accretion in the TW Hya Star/Disk System
J. A. Eisner, G. W. Doppmann, J. R. Najita +4
We present two epochs of observations of TW Hya from the high-dispersion near-IR spectrograph ARIES at the MMT. We detect strong emission from the Brackett gamma transition of hydr…
SuperCAM CO(3-2) APEX survey at 6 pc resolution in the Small Magellanic Clouds
H. P. Saldaño, M. Rubio, A. D. Bolatto +9
We present the CO(3-2) APEX survey at 6 pc resolution of the bar of the SMC. We aboard the CO analysis in the SMC-Bar comparing the CO(3-2) survey with that of the CO(2-1) of simil…
The absolute age of the globular cluster M15 using near-infrared adaptive optics images from PISCES/LBT
M. Monelli, V. Testa, G. Bono +26
We present deep near-infrared (NIR) J, Ks photometry of the old, metal-poor Galactic globular cluster M\,15 obtained with images collected with the LUCI1 and PISCES cameras availab…
LBT observations of the HR 8799 planetary system: First detection of HR8799e in H band
S. Esposito, D. Mesa, A. Skemer +33
We have performed H and Ks band observations of the planetary system around HR 8799 using the new AO system at the Large Binocular Telescope and the PISCES Camera. The excellent in…
High Resolution Images of Orbital Motion in the Orion Trapezium Cluster with the LBT Adaptive Optics System
L. M. Close, A. Puglisi, J. R. Males +28
The new 8.4m LBT adaptive secondary AO system, with its novel pyramid wavefront sensor, was used to produce very high Strehl (75% at 2.16 microns) near infrared narrowband (Br gamm…
The VAST Survey - IV. A wide brown dwarf companion to the A3V star Delphini
R. J. De Rosa, J. Patience, K. Ward-Duong +10
We report the discovery of a wide co-moving substellar companion to the nearby ( pc) A3V star Delphini based on imaging and follow-up spectroscopic observations…
CO Line Emission and Absorption from the HL Tau Disk: Where is all the dust?
S. Brittain, T. Rettig, T. Simon +1
We present high-resolution infrared spectra of HL Tau, a heavily embedded young star. The spectra exhibit broad emission lines of hot CO gas as well as narrow absorption lines of c…
The APEX Large CO Heterodyne Orion Legacy Survey (ALCOHOLS). I. Survey overview
Thomas Stanke, H. G. Arce, J. Bally +29
The Orion molecular cloud complex harbours the nearest GMCs and site of high-mass star formation. Its YSO populations are thoroughly characterized. The region is therefore a prime…
The M-dwarfs in Multiples (MinMs) survey - I. Stellar multiplicity among low-mass stars within 15 pc
K. Ward-Duong, J. Patience, R. J. De Rosa +6
We present a large-scale, volume-limited companion survey of 245 late-K to mid-M (K7-M6) dwarfs within 15 pc. Infrared adaptive optics (AO) data were analysed from the Very Large T…
Dust Stratification in Young Circumstellar Disks
T. Rettig, S. Brittain, Theodore Simon +4
We present high-resolution infrared spectra of four YSOs (T Tau N, T Tau S, RNO 91, and HL Tau). The spectra exhibit narrow absorption lines of 12CO, 13CO, and C18O as well as broa…
