Hydrogen isotope exchanges between water and methanol in interstellar ices

A. Faure, M. Faure, P. Theulé +2

The deuterium fractionation of gas-phase molecules in hot cores is believed to reflect the composition of interstellar ices. The deuteration of methanol is a major puzzle, however,…

HD141569A: disk dissipation caught in action

J. Péricaud, E. Di Folco, A. Dutrey +3

Debris disks are usually thought to be gas-poor, the gas being dissipated by accretion or evaporation during the protoplanetary phase. HD141569A is a 5 Myr old star harboring a fam…

An M-dwarf star in the transition disk of Herbig HD 142527; Physical parameters and orbital elements

S. Lacour, B. Biller, A. Cheetham +29

HD 142527A is one of the most studied Herbig Ae/Be stars with a transitional disk, as it has the largest imaged gap in any protoplanetary disk: the gas is cleared from 30 to 90 AU.…

Mid-IR spectra of Pre-Main Sequence Herbig stars: an explanation for the non-detections of water lines

S. Antonellini, I. Kamp, F. Lahuis +7

The mid-IR detection rate of water lines in disks around Herbig stars disks is about 5\%, while it is around 50\% for disks around TTauri stars. The reason for this is still unclea…
