X-rays from shock-heated gas in recurrent-nova remnants: Nested nova shells in a structured circumstellar medium
Sergio Martínez-González, Santiago Jiménez, Richard Wünsch +1
Recurrent symbiotic novae such as RS Oph show extended X-ray emission associated with the interaction of nova ejecta with the circumstellar environment. We investigate how repeated…

Mechanical Torque Disruption of Dust Grains Induced by Supernova Shock Waves
Sergio MartÃnez-González
The feedback from massive stars drives the evolution of interstellar dust grains by altering their physical properties via a number of radiative and mechanical processes. Through t…

The bright, dusty aftermath of giant eruptions & H-rich supernovae. Late interaction of supernova shocks & dusty circumstellar shells
Diana B. Serrano-Hernández, Sergio MartÃnez-González, Santiago Jiménez +2
The late-stage evolution of massive stars is marked by intense instability as they approach core-collapse. During these phases, giant stellar eruptions lead to exceptionally high m…
