A first catalogue of automatically selected UV-excess sources from the UVEX survey

Kars Verbeek, Eelco de Groot, Paul J. Groot +10

We present the first catalogue of point-source UV-excess sources selected from the UVEX survey. UVEX images the Northern Galactic Plane in the U, g, r and HeI5875 bands in the Gala…

A Herschel Search For Cold Dust in Brown Dwarf Disks: First Results

Paul M. Harvey, Thomas Henning, Francois Menard +7

We report initial results from a {\it Herschel} program to search for far-infrared emission from cold dust around a statistically significant sample of young brown dwarfs. The firs…

First Results from Pan-STARRS1: Faint, High Proper Motion White Dwarfs in the Medium-Deep Fields

J. L. Tonry, C. W. Stubbs, M. Kilic +13

The Pan-STARRS1 survey has obtained multi-epoch imaging in five bands (Pan-STARRS1 gps, rps, ips, zps, and yps) on twelve "Medium Deep Fields", each of which spans a 3.3 degree cir…

HIP 38939B: A New Benchmark T Dwarf in the Galactic Plane Discovered with Pan-STARRS1

Niall R. Deacon, Michael C. Liu, Eugene A. Magnier +13

We report the discovery of a wide brown dwarf companion to the mildly metal-poor ([Fe/H]=-0.24), low galactic latitude (b = 1.88 deg) K4V star HIP 38939. The companion was discover…

Classifying structures in the ISM with Support Vector Machines: the G16.05-0.57 supernova remnant

Christopher N. Beaumont, Jonathan P. Williams, Alyssa A. Goodman

We apply Support Vector Machines -- a machine learning algorithm -- to the task of classifying structures in the Interstellar Medium. As a case study, we present a position-positio…

The mm-colors of a young binary disk system in the Orion Nebula Cluster

L. Ricci, L. Testi, J. P. Williams +2

We present new EVLA continuum observations at 7 mm of the 253-1536 binary disk system in the Orion Nebula Cluster. The measured fluxes were combined with data in the sub-mm to deri…

Searching for new hypercompact HII regions

Alvaro Sanchez-Monge, Jagadheep D. Pandian, Stan Kurtz

Hypercompact (HC) HII regions are, by nature, very young HII regions, associated with the earliest stages of massive star formation. They may represent the transition phase as an e…

Planetary nebulae in the elliptical galaxy NGC 4649 (M 60): kinematics and distance redetermination

A. M. Teodorescu, R. H. Mendez, F. Bernardi +3

Using a slitless spectroscopy method with (a) the 8.2 m Subaru telescope and its FOCAS Cassegrain spectrograph, and (b) the ESO Very Large Telescope (VLT) unit 1 (Antu) and its FOR…

Massive stars in the Cl 1813-178 Cluster. An episode of massive star formation in the W33 complex

Maria Messineo, Ben Davies, Donald F. Figer +5

Young massive (M >10^4 Msun) stellar clusters are a good laboratory to study the evolution of massive stars. Only a dozen of such clusters are known in the Galaxy. Here we report a…

Protoplanetary Disks and Their Evolution

Jonathan P. Williams, Lucas A. Cieza

Flattened, rotating disks of cool dust and gas extending for tens to hundreds of AU are found around almost all low mass stars shortly after their birth. These disks generally pers…

Spatially Resolved Spectroscopic Observations of a Possible E+A Progenitor SDSS J160241.00+521426.9

Kazuya Matsubayashi, Masafumi Yagi, Tomotsugu Goto +5

In order to investigate the evolution of E+A galaxies, we observed a galaxy SDSS J160241.00+521426.9, a possible E+A progenitor which shows both emission and strong Balmer absorpti…

The HST/ACS Coma Cluster Survey IV. Intergalactic Globular Clusters and the Massive Globular Cluster System at the Core of the Coma Galaxy Cluster

Eric W. Peng, Henry C. Ferguson, Paul Goudfrooij +21

Intracluster stellar populations are a natural result of tidal interactions in galaxy clusters. Measuring these populations is difficult, but important for understanding the assemb…
