Application limit of the photocentre displacement to fundamental stellar parameters of fast rotators -- Illustration on the edge-on fast rotator Regulus
M. Hadjara, R. G. Petrov, S. Jankov +16
Differential Interferometry allows to obtain the differential visibility and phase, in addition to the spectrum. The differential phase contains important information about the str…
Chandra Observations of SNR 1987A
S. Park, D. N. Burrows, S. A. Zhekov +3
We report on the results of our monitoring program of the X-ray remnant of supernova 1987A with the {\it Chandra X-Ray Observatory}. We have performed two new observations during t…
Modelling the Hubble Space Telescope Ultraviolet and Optical Spectrum of Spot 1 on the Circumstellar Ring of SN 1987A
Chun S. J. Pun, Eli Michael, Svetozar A. Zhekov +18
We report and interpret HST/STIS long-slit observations of the optical and ultraviolet (1150 - 10270 Angstrom) emission-line spectra of the rapidly brightening Spot 1 on the equato…
The X-ray Spectrum of Supernova Remnant 1987A
Eli Michael, Svetozar Zhekov, Richard McCray +6
We discuss the X-ray emission observed from Supernova Remnant 1987A with the Chandra X-ray Observatory. We analyze a high resolution spectrum obtained in 1999 October with the high…
Monitoring the Evolution of the X-ray Remnant of SN 1987A
Sangwook Park, David N. Burrows, Gordon P. Garmire +4
We report on the results of our monitoring program of the remnant of SN 1987A with the Advanced CCD Imaging Spectrometer (ACIS) on board the {\it Chandra X-ray Observatory}. Two ne…
Analysis of the Type IIn Supernova 1998S: Effects of Circumstellar Interaction on Observed Spectra
Eric J. Lentz, E. Baron, Peter Lundqvist +20
We present spectral analysis of early observations of the Type IIn supernova 1998S using the general non-local thermodynamic equilibrium atmosphere code \tt PHOENIX}. We model both…
