Laboratory unraveling of matter accretion in young stars

2017

When matter accretes onto a young star, a shell of dense material can form around the impact, reducing its x-ray emission.

Inferring possible magnetic field strength of accreting inflows in EXor-type objects from scaled laboratory experiments

2021

Aims. EXor-type objects are protostars that display powerful UV-optical outbursts caused by intermittent and powerful events of magnetospheric accretion. These objects are not yet well investigated and are quite difficult to characterize. Several parameters, such as plasma stream velocities, characteristic densities, and temperatures, can be retrieved from present observations. As of yet, however, there is no information about the magnetic field values and the exact underlying accretion scenario is also under discussion. Methods. We use laboratory plasmas, created by a high power laser impacting a solid target or by a plasma gun injector, and make these plasmas propagate perpendicularly to …
