Discovery of unusual pulsations in the cool, evolved Am stars HD 98851 and HD 102480
Santosh Joshi, V. Girish, R. Sagar +6
The chemically peculiar (CP) stars HD 98851 and HD 102480 have been discovered to be unusual pulsators during the ``Naini Tal Cape Survey'' programme to search for pulsational vari…
Correlated radio:X-ray emission in the hard states of Galactic microquasars
M. Choudhury, A. R. Rao, S. V. Vadawale +1
We present results of our study of correlated radio and X-ray emission in two black hole candidates and Galactic microquasars GRS 1915+105 and Cygnus X-1 in their steady long term…
Amplitude and frequency variability of the pulsating DB white dwarf stars KUV 05134+2605 and PG 1654+160 observed with the Whole Earth Telescope
G. Handler
We have acquired new time series photometry of the two pulsating DB white dwarf stars KUV 05134+2605 and PG 1654+160 with the Whole Earth Telescope. Additional single-site photomet…
X-ray spectral evolution of low-mass X-ray binary GX 349+2
V. K. Agrawal, P. Sreekumar
We present the results of a systematic investigation of spectral evolution in the Z source GX 349+2, using data obtained during 1998 with Proportional-Counter-Array (PCA) on-board…
EGRET upper limits on the high-energy gamma-ray emission of galaxy clusters
O. Reimer, M. Pohl, P. Sreekumar +1
We report EGRET upper limits on the high-energy gamma-ray emission from clusters of galaxies. EGRET observations between 1991 and 2000 were analyzed at positions of 58 individual c…
