Low resolution spectroscopy of selected Algol systems
D. Shanti Priya, J. Rukmini, M. Parthasarathy +4
The analysis of spectroscopic data for 30 Algol-type binaries is presented. All these systems are short period Algols having primaries with spectral types B and A. Dominant spectra…
Study of the plutino object (208996) 2003 AZ84 from stellar occultations: size, shape and topographic features
A. Dias-Oliveira, B. Sicardy, J. L. Ortiz +60
We present results derived from four stellar occultations by the plutino object (208996) 2003~AZ, detected at January 8, 2011 (single-chord event), February 3, 2012 (multi-c…
SALT observation of X-ray pulse reprocessing in 4U 1626-67
Gayathri Raman, Biswajit Paul, Dipankar Bhattacharya +1
We investigate optical reprocessing of X-rays in the LMXB pulsar 4U 1626-67 in its current spin-up phase using observations with Southern African Large Telescope (SALT), near-simul…
Molecular hydrogen from z = 0.0963 DLA towards the QSO J1619+3342
Raghunathan Srianand, Hadi Rahmani, Sowgat Muzahid +1
We report the detection of H2 in a zabs= 0.0963 Damped Lyman-α (DLA) system towards zem = 0.4716 QSO J1619+3342. This DLA has log N(H I) = 20.55 (0.10), 18.13 < log N(H2) < 18.40,…
The outburst and nature of young eruptive low mass stars in dark clouds
J. P. Ninan, D. K. Ojha, B. C. Bhatt +5
The FU Orionis (FUor) or EX Orionis (EXor) phenomenon has attracted increasing attention in recent years and is now accepted as a crucial element in the early evolution of low-mass…
Highly Ionized Collimated Outflow from HE 0238 - 1904
Sowgat Muzahid, Raghunathan Srianand, Blair D. Savage +3
We present a detailed analysis of a highly ionized, multiphased and collimated outflowing gas detected through O V, O VI, Ne VIII and Mg X absorption associated with the QSO HE 023…
