COUP census of X-ray stars in BN-KL and OMC-1S
N. Grosso, E. D. Feigelson, K. V. Getman +11
We present a study of the X-ray sources detected in the vicinity of two density peaks in the Orion Molecular Cloud 1 (OMC-1) behind the Orion Nebula Cluster (ONC), as seen in the e…
The double-lined spectroscopic binary alpha Andromedae: orbital elements and elemental abundances
T. Ryabchikova, V. Malanushenko, S. J. Adelman
We performed a spectroscopic study of the SB2 Mercury-Manganese star alpha And. Our measurements of the secondary's radial velocities result in improved orbital elements. The secon…
Discovery of the secondary star of the HgMn binary kappa Cancri
T. Ryabchikova, O. Kotchoukhov, G. Galazutdinov +2
A careful investigation of a CCD spectrum of the SB1 system kappa Cnc in the spectral region 3800 A - 8000 A resulted in the discovery of the lines of the secondary star. We then a…
Supersonic Random Flows in the Perseus Molecular Cloud
Paolo Padoan, John Bally, Youssef Billawala +2
We compare the statistical properties of J=1-0 13CO spectra observed in the Perseus Molecular Cloud with synthetic J=1-0 13CO spectra from a 5 pc model cloud. The synthetic spectra…
