Optical and Infrared Spectroscopy of the type IIn SN 1998S : Days 3-127
A. Fassia, W. P. S. Meikle, N. Chugai +14
We present contemporary infrared and optical spectroscopic observations of the type IIn SN 1998S for the period between 3 and 127 days after discovery. In the first week the spectr…
Chemical abundances in the inner 5 kpc of the Galactic disk
S. J. Smartt, K. A. Venn, P. L. Dufton +3
High-resolution, high signal-to-noise spectral data are presented for four young B-type stars lying towards the Galactic Centre. Determination of their atmospheric parameters from…
Chemical abundances and winds of massive stars in M31: a B-type supergiant and a WC star in OB10
S. J. Smartt, P. A. Crowther, P. L. Dufton +5
We present high quality spectroscopic data for two massive stars in the OB10 association of M31, OB10-64 (B0Ia) and OB10-WR1 (WC6). Medium resolution spectra of both stars were obt…
Interstellar X-ray Absorption Spectroscopy of Oxygen, Neon, and Iron with the Chandra LETGS Spectrum of X0614+091
Frits Paerels, A. C. Brinkman, R. L. J. van der Meer +8
We find resolved interstellar O K, Ne K, and Fe L absorption spectra in the Chandra Low Energy Transmission Grating Spectrometer spectrum of the low mass X-ray binary X0614+091. We…
Magnetic Activity in Stars, Discs and Quasars
Donald Lynden-Bell
Although magnetic fields in interstellar matter were postulated almost fifty years ago, magnetohydrodynamic theory was then much hampered by our inability to see what the magnetic…
An Early-Time Infrared and Optical Study of the Type Ia Supernova 1998bu in M96
M. Hernandez, W. P. S. Meikle, A. Aparicio +22
We present first-season infrared (IR) and optical photometry and spectroscopy of the Type Ia Supernova 1998bu in M96. We also report optical polarimetry of this event. SN1998bu is…
Optical and Infrared photometry of the type IIn SN 1998S:Days 11-146
A. Fassia, W. P. S. Meikle, W. D. Vacca +1
We present contemporaneous optical and infrared photometric observations of the type IIn SN 1998S covering the period between 11 and 146 days after discovery. The infrared data con…
Radial velocities of pulsating subdwarf B stars: KPD 2109+4401 and PB 8783
Simon Jeffery, Don Pollacco
High-speed spectroscopy of two pulsating subdwarf B stars, KPD 2109+4401 and PB 8783, is presented. Radial motions are detected with the same frequencies as reported from photometr…
WR146 - observing the OB-type companion
Sean M. Dougherty, P. M. Williams, D. L. Pollacco
We present new radio and optical observations of the colliding-wind system WR146 aimed at understanding the nature of the companion to the Wolf-Rayet star and the collision of thei…
Search and Discovery Tools for Astronomical On-line Resources and Services
Daniel Egret, Robert J. Hanisch, Fionn Murtagh
A growing number of astronomical resources and data or information services are made available through the Internet. However valuable information is frequently hidden in a deluge o…
