The role of supernova remnants for the emergence of pre-biotic chemistry in molecular clouds

Giuliana Cosentino, Izaskun Jiménez-Serra, Laura Colzi +11

There is growing evidence that the Sun might have formed within a nebula impacted by at least one SNR. In this scenario, ejecta and shocks from SNRs may have provided the elements…

High deuteration of methanol in L1544

S. Spezzano, W. Riedel, P. Caselli +7

Isotopic fractionation is a very powerful tool to follow the evolution of material from one stage to the next in the star-formation process. Pre-stellar cores exhibit some of the h…

Chemical complexity in star formation induced by stellar feedback: cores shock-formed by the supernova remnant W44

G. Cosentino, I. Jiménez-Serra, F. Fontani +8

Low-velocity shocks from Supernova Remnants (SNRs) may set the physical and chemical conditions of star formation in molecular clouds. Recent evidence suggests that the Sun might h…

Multiple outflows and delayed ejections revealed by early imaging of novae

Elias Aydi, John D. Monnier, Antoine Mérand +39

Novae are thermonuclear eruptions on accreting white dwarfs in interacting binaries. Although most of the accreted envelope is expelled, the mechanism -- impulsive ejection, multip…

Stellar feedback drives the baryon deficiency in low-mass galaxies

Haoran Yu, Enci Wang, Zeyu Chen +8

Stellar feedback, as a key process regulating the baryon cycle, is thought to greatly redistribute baryonic material inside and outside the dark matter halos (DMHs), however the ob…
