Water abundances in high-mass protostellar envelopes: Herschel observations with HIFI [PDF]

, 2010
We derive the dense core structure and the water abundance in four massive star-forming regions which may help understand the earliest stages of massive star formation. We present Herschel-HIFI observations of the para-H2O 1_11-0_00 and 2_02-1_11 and the

Doppler shift of hot coronal lines in a moss area of an active region [PDF]

, 2012
The moss is the area at the footpoint of the hot (3 to 5 MK) loops forming the core of the active region where emission is believed to result from the heat flux conducted down to the transition region from the hot loops. Studying the variation of Doppler
