AstroSat Science Support Cell
J. Roy, Md S. Alam, C. Balamurugan +7
AstroSat is India's first dedicated multi-wavelength space observatory launched by the Indian Space Research Organisation (ISRO) on 28 September 2015. After launch, the AstroSat Sc…
The K-band Spectrum of The Hot Star in IRS~8: An Outsider in the Galactic Center?
T. R. Geballe, F. Najarro, F. Rigaut +1
Using adaptive optics at the Gemini North telescope we have obtained a K-band spectrum of the star near the center of the luminous Galactic center bowshock IRS8, as well as a spect…
Physical parameters of erupting Luminous Blue Variables: NGC 2363-V1 caught in the act
L. Drissen, P. A. Crowther, L. J. Smith +3
A quantitative study of the Luminous Blue Variable NGC 2363-V1 in the Magellanic galaxy NGC 2366 (D = 3.44 Mpc) is presented, based on ultraviolet and optical HST/STIS spectroscopy…
A continuous low star formation rate in IZw 18 ?
F. Legrand, D. Kunth, J. -R. Roy +2
Deep long-slit spectroscopic observations of the blue compact galaxy IZw 18 obtained with the CFH 3.6 m Telescope are presented. The very low value of oxygen abundance previously r…
The Star Formation History of the Starburst Region NGC 2363 and its Surroundings
L. Drissen, J. -R. Roy, C. Robert +2
We present HST optical images and UV spectra, as well as ground-based near-infrared images of the high surface brightness giant HII region NGC 2363 (NGC 2366-I) and its surrounding…
Chemical evolution of low mass disc galaxies
Mercedes Molla, Jean-Rene Roy
We show that the multiphase chemical evolution model reproduces the correlations obtained along the spiral sequence, dwarf galaxies included. However the apparent spatial chemical…
