Origin of CH+ in diffuse molecular clouds warm H2 and ion-neutral drift
Valeska Valdivia, Benjamin Godard, Patrick Hennebelle +3
This paper assesses the roles of the presence of warm H2, and the increased formation rate due to the ion-neutral drift. We performed ideal MHD simulations that include the heating…
Spiral-driven accretion in protoplanetary discs - III tri-dimensional simulations
Patrick Hennebelle, Geoffroy Lesur, Sébastien Fromang
Understanding how accretion proceeds in proto-planetary discs and more generally their dynamics is a crucial issue for explaining the conditions in which planets form. The role tha…
First image of the L1157 molecular jet by the CALYPSO IRAM-PdBI survey
L. Podio, C. Codella, F. Gueth +12
Fast jets are thought to be a crucial ingredient of star formation because they might extract angular momentum from the disk and thus allow mass accretion onto the star. However, i…
Magnetically self-regulated formation of early protoplanetary discs
Patrick Hennebelle, Benoit Commercon, Gilles Chabrier +1
The formation of protoplanetary discs during the collapse of molecular dense cores is significantly influenced by angular momentum transport, notably by the magnetic torque. In tur…
Feedback in Clouds II: UV Photoionisation and the first supernova in a massive cloud
Sam Geen, Patrick Hennebelle, Pascal Tremblin +1
Molecular cloud structure is regulated by stellar feedback in various forms. Two of the most important feedback processes are UV photoionisation and supernovae from massive stars.…
A chemical solver to compute molecule and grain abundances and non-ideal MHD resistivities in prestellar core collapse calculations
Pierre Marchand, Jacques Masson, Gilles Chabrier +3
We develop a detailed chemical network relevant to the conditions characteristic of prestellar core collapse. We solve the system of time-dependent differential equations to calcul…
