Radio Emission from the Double-Pulsar System J0737-3039 Revisited

S. Chatterjee, W. M. Goss, W. F. Brisken

The double pulsar J0737-3039 is the only known system in which the relativistic wind emitted by a radio pulsar demonstrably interacts with the magnetosphere of another one. We repo…

SDSS J124058.03-015919.2: A new AM CVn star with a 37-minute orbital period

G. H. A. Roelofs, P. J. Groot, T. R. Marsh +3

We present high time resolution VLT spectroscopy of SDSS J124058.03-015919.2, a new helium-transferring binary star identified in the Sloan Digital Sky Survey. We measure an orbita…

Probing the Local Group Medium Toward Mkn 421 with Chandra and FUSE

Rik J. Williams, Smita Mathur, Fabrizio Nicastro +7

We report the detection of highly-ionized gas at z~0 seen in resonant UV and X-ray absorption lines toward the z=0.03 blazar Mkn 421. A total of 13 X-ray and 3 UV lines were measur…

Mass-loss and Recent Spectral Changes in the Yellow Hypergiant Rho Cassiopeiae

A. Lobel, J. Aufdenberg, I. Ilyin +1

The yellow hypergiant Rho Cassiopeiae (F-G Ia0) has recently become very active with a tremendous outburst event in the fall of 2000. During the event the pulsating supergiant dimm…
