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…

The Star Formation Factory revisited I. The impact of metallicity on collapsing star-forming clouds
S. Jiménez, D. Kománek, R. Wünsch +4
Context. Stellar feedback regulates star formation and shapes the interstellar medium, yet its role during the collapse of molecular clouds remains uncertain over a wide range of i…

The bright, dusty aftermath of giant eruptions & H-rich supernovae. Late interaction of supernova shocks & dusty circumstellar shells
Diana B. Serrano-Hernández, Sergio Martínez-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…
