Opening the Treasure Chest: A Newborn Star Cluster Emerges from its Dust Pillar in Carina
Nathan Smith, Keivan G. Stassun, John Bally
We present detailed observations of the Treasure Chest, a compact nebula at the head of a dust pillar in the southern Carina nebula. This object is of interest because it is an exa…
Can photo-evaporation trigger planetesimal formation?
Henry B. Throop, John Bally
We propose that UV radiation can stimulate the formation of planetesimals in externally-illuminated protoplanetary disks. We present a numerical model of disk evolution including v…
New Silhouette Disks with Reflection Nebulae and Outflows in the Orion Nebula and M43
Nathan Smith, John Bally, Daniel Licht +1
We report the detection of several new circumstellar disks seen in silhouette in the outskirts of the Orion nebula and M43, detected as part of our Halpha survey of Orion with the…
Chandra Orion Ultradeep Project: Observations and Source Lists
K. V. Getman, E. Flaccomio, P. S. Broos +21
We present a description of the data reduction methods and the derived catalog of more than 1600 X-ray point sources from the exceptionally deep January 2003 Chandra X-ray Observat…
Thermal-IR Detection of Optical Outflow Sources in OMC1 South
Nathan Smith, John Bally, Ralph Y. Shuping +2
We present the first thermal-infrared imaging photometry for several embedded sources in the OMC1 South cloud core in the Orion nebula, and propose that some of these drive optical…
A new mid-infrared map of the BN/KL region using the Keck telescope
R. Y. Shuping, Mark Morris, John Bally
We present a new mid-infrared (12.5micron) map of the BN/KL high-mass star-forming complex in Orion using the LWS instrument at Keck I. Despite poor weather we achieved nearly diff…
