Probing the Physics of Star-Formation (ProPStar): II. The first systematic search for streamers toward protostars
María Teresa Valdivia-Mena, Jaime E. Pineda, Paola Caselli +9
The detection of narrow channels of accretion toward protostellar disks, known as streamers, have increased in number in the last few years. However, it is unclear if streamers are…
Probing the physics of star formation (ProPStar): I. First resolved maps of the electron fraction and cosmic-ray ionization rate in NGC 1333
Jaime E. Pineda, Olli Sipilä, Dominique M. Segura-Cox +11
Electron fraction and cosmic-ray ionization rates (CRIR) in star-forming regions are important quantities in astrochemical modeling and are critical to the degree of coupling betwe…
Dust grains cannot grow to millimeter sizes in protostellar envelopes
Kedron Silsbee, Vitaly Akimkin, Alexei V. Ivlev +3
A big question in the field of star and planet formation is the time at which substantial dust grain growth occurs. The observed properties of dust emission across different wavele…
Cosmic rays in molecular clouds probed by H rovibrational lines -- Perspectives for the James Webb Space Telescope
Marco Padovani, Shmuel Bialy, Daniele Galli +7
Cosmic rays (CRs) at sub-TeV energies play a fundamental role in the chemical and dynamical evolution of molecular clouds, as they control the ionisation, dissociation, and excitat…
The cosmic-ray ionisation rate in the pre-stellar core L1544
Elena Redaelli, Olli Sipilä, Marco Padovani +3
Context. Cosmic rays (CRs) play an important role in the chemistry and dynamics of the interstellar medium. In dense environments, they represent the main ionising agent, driving t…
Ice mantles on dust grains: dramatic variation of thickness with grain size
Kedron Silsbee, Paola Caselli, Alexei V. Ivlev
We compute the desorption rate of icy mantles on dust grains as a function of the size and composition of both the grain and the mantle. We combine existing models of cosmic ray (C…
