A CH3CN and HCO+ survey towards southern methanol masers associated with star formation
C. R. Purcell, R. Balasubramanyam, M. G. Burton +32
We present the initial results of a 3-mm spectral line survey towards 83 methanol maser selected massive star-forming regions. Here we report observations of the J=5-4 and 6-5 rota…
The origin of the double main sequence in Omega Centauri: Helium enrichment due to gas fueling from its ancient host galaxy ?
Kenji Bekki, John E. Norris
Recent observational studies of Centauri by {\it Hubble Space Telescope} have discovered a double main sequence in the color magnitude diagrams (CMDs) of its stellar population…
Oxygen abundances in metal-poor subgiants as determined from [O I], O I and OH lines
A. E. García Pérez, M. Asplund, F. Primas +2
The debate on the oxygen abundances of metal-poor stars has its origin in contradictory results obtained using different abundance indicators. To achieve a better understanding of…
Infrared Spectroscopy of Symbiotic Stars. IV. V2116 Ophiuchi/GX 1+4, The Neutron Star Symbiotic
Kenneth H. Hinkle, Francis C. Fekel, Richard R. Joyce +3
We have computed, based on 17 infrared radial velocities, the first set of orbital elements for the M giant in the symbiotic binary V2116 Ophiuchi. The giant's companion is a neutr…
Reverberation Measurements of the Inner Radius of the Dust Torus in Nearby Seyfert 1 Galaxies
M. Suganuma, Y. Yoshii, Y. Kobayashi +6
The most intense monitoring observations yet made in the optical (UBV) and near-infrared (JHK) wave bands were carried out for nearby Seyfert1 galaxies of NGC 5548, NGC 4051, NGC 3…
Reconciling the local galaxy population with damped Ly-alpha cross sections and metal abundances
M. A. Zwaan, J. M. van der Hulst, F. H. Briggs +2
A comprehensive analysis of 355 high-quality WSRT HI 21-cm line maps of nearby galaxies shows that the properties and incident rate of Damped Lyman-alpha (DLA) absorption systems o…
