Carbon-rich dust past the asymptotic giant branch: aliphatics, aromatics, and fullerenes in the Magellanic Clouds
G. C. Sloan, E. Lagadec, A. A. Zijlstra +10
Infrared spectra of carbon-rich objects which have evolved off the asymptotic giant branch reveal a range of dust properties, including fullerenes, polycyclic aromatic hydrocarbons…
The low wind expansion velocity of metal-poor carbon stars in the Halo and the Sagittarius stream
Eric Lagadec, Albert Zijlstra, Nicolas Mauron +4
We report the detection, from observations using the James Clerk Maxwell Telescope, of CO J 3 2 transition lines in six carbon stars, selected as members of the Galactic H…
A Survey of Local Group Galaxies Currently Forming Stars: III. A Search for Luminous Blue Variables and Other H-alpha Emission-Lined Stars
Philip Massey, Reagin T. McNill, K. A. G. Olsen +5
We describe a search for H-alpha emission-lined stars in M31, M33, and seven dwarfs in or near the Local Group (IC 10, NGC 6822, WLM, Sextans B, Sextans A, Pegasus and the Phoenix…
New Distant Companions to Known Nearby Stars. II. Faint companions of Hipparcos stars and the frequency of wide binary systems
Sebastien Lepine, Bethany Bongiorno
We perform a search for faint, common proper motion companions of Hipparcos stars using the recently published LSPM-north catalog of stars with proper motion mu>0.15 arcsec/yr. Our…
The Recurrent Eclipse of an Unusual Pre--Main-Sequence Star in IC 348
S. Nordhagen, W. Herbst, E. C. Williams +1
The recurrence of a previously documented eclipse of a solar-like pre--main-sequence star in the young cluster IC 348 has been observed. The recurrence interval is 4.7 yr…
The Variability and Rotation of Pre-main Sequence Stars in IC 348: Does Intracluster Environment Influence Stellar Rotation?
S. Nordhagen, W. Herbst, K. L. Rhode +1
A variability study of the young cluster IC 348 at Van Vleck Observatory has been extended to a total of seven years. Twelve new periodic stars have been found in the last two year…
