A search for circumstellar gas in pre-main-sequence debris discs using absorption spectroscopy
Karolina M. Szewczyk, Daniela P. Iglesias, Olja PaniÄ
Gas in debris discs is thought to be either inherited from the protoplanetary stage or released from the solid, rocky content of planetesimal belts. Its presence can impact planeta…

HD 44892: The youngest (or oldest?) gas-harbouring debris disc around an intermediate mass star
Karolina M. Szewczyk, Olja PaniÄ, Daniela P. Iglesias +2
We present the first detections of gas around a 2.1 Myr old debris disc-bearing intermediate-mass star, HD 44892. Gas is detected both in CO (2-1) emission through ALMA Band…
