Tidal Tails in Interacting Galaxies: Formation of Compact Stellar Structures
B. Mullan, J. C. Charlton, I. S. Konstantopoulos +17
We have used V- and I- band images from the Hubble Space Telescope (HST) to identify compact stellar clusters within the tidal tails of twelve different interacting galaxies. The s…
Evidence for an Edge-On Disk around the Young Star MWC 778 from Infrared Imaging and Polarimetry
Marshall D. Perrin, William D. Vacca, James R. Graham
MWC 778 is an unusual and little-studied young stellar object located in the IC 2144 nebula. Recent spectroscopy by Herbig and Vacca (2008) suggested the presence of an edge-on cir…
The Unusual Object IC 2144/MWC 778
G. H. Herbig, William D. Vacca
IC 2144 is a small reflection nebula located in the zone of avoidance near the Galactic anticenter. It has been investigated here largely on the basis of Keck/HIRES optical spectro…
Young star clusters in interacting galaxies - NGC 1487 and NGC 4038/4039
Sabine Mengel, Matthew D. Lehnert, Niranjan A. Thatte +3
We estimate the dynamical masses of several young (~10 Myr) massive star clusters in two interacting galaxies, NGC 4038/4039 ("The Antennae") and NGC 1487, under the assumption of…
Oph 1622-2405: Not a Planetary-Mass Binary
K. L. Luhman, K. N. Allers, D. T. Jaffe +4
We present an analysis of the mass and age of the young low-mass binary Oph 1622-2405. Using resolved optical spectroscopy of the binary, we measure spectral types of M7.25+/-0.25…
A census of the Wolf-Rayet content in Westerlund 1 from near-infrared imaging and spectroscopy
Paul A. Crowther, L. J. Hadfield, J. S. Clark +2
New NTT/SOFI imaging and spectroscopy of the Wolf-Rayet population in Westerlund 1 are presented. Narrow-band near-IR imaging together with follow up spectroscopy reveals four new…
