The angular momentum of condensations within elephant trunks

The angular momentum of condensations within elephant trunks

Aims. The radiation from newly born stars photoevaporates their parental neutral cloud, leading to the formation of dense clumps that will eventually form stars. Methods. We present 3D simulations of the interaction of a neutral cloud with an external ionising radiation field, and compute the angular momenta of these collapsing clumps. Results. The angular momenta of these collapsing clumps sho...

Hh Jets Aligned Perpendicular to Elephant Trunks

We consider a system of outflows ejected from low mass young stars embedded in the tips of elephant trunks. We assume that these outflows have axes which are intrinsically perpendicular to the axes of the host elephant trunks. We then derive the distribution function expected for the angle between the projections of the outflow and elephant trunk axes on the plane of the sky. These distribution...

Elephant trunks in aortic surgery: fresh and frozen.

Aneurysmal diseases are often silent but can cause potentially life-threatening complications in cases of dissection or rupture. Surgical strategies depend on the involved part of the aorta and frequently require extracorporeal circulation and circulatory arrest. From data available from the Centers for Disease Control and Prevention, aneurysm disease is the 18th most common cause of death in a...
