Comparative spectro-temporal study between 1A 1246 − 588 and 4U 0614 + 091 using AstroSat

We present a comparative broadband spectro-temporal study of the ultra-compact X-ray binary (UCXB) candidates 1A 1246 − 588 and 4U 0614 + 091 using AstroSat observations. Spectral modelling shows that the spectrum of 1A 1246 − 588 is well described by thermal Comptonization and a...
