Investigative study of five low mass ratio semi-detached binaries

Stassun, Keivan G.; Parthasarathy, Mudumba; Jagirdar, Rukmini +2 more

We present the first pulsation analysis of four totally eclipsing Algol systems S Cnc, SS Cet, TW And, and VW Cyg using the latest data available from Kepler (K2), and TESS databases. Based on the characteristics observed they are classified to be oscillating eclipsing Algol binaries with primary components having

Radio continuum emission from planetary nebulae in the Small Magellanic Cloud

Filipović, M. D.; Crawford, E. J.; Bojičić, I. +3 more

We report 11 new radio continuum measurements of established planetary nebulae (PNe) in the Small Magellanic Cloud (SMC) that we observed at 5.5 and 9 GHz with the Australia Telescope Compact Array (ATCA). These new radio detections are PNe with catalogued names: SMP SMC 2, SMP SMC 3, SMP SMC 5, SMP SMC 8, SMP SMC 13, SMP SMC 14, SMP SMC 19, MGPN …
