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…
Coagulation-Fragmentation Equilibrium for Charged Dust: Abundance of Submicron Grains Increases Dramatically in Protoplanetary Disks
Vitaly Akimkin, Alexei V. Ivlev, Paola Caselli +2
Dust coagulation in protoplanetary disks is not straightforward and is subject to several slow-down mechanisms, such as bouncing, fragmentation and radial drift to the star. Furthe…
Bombardment of CO ice by cosmic rays: I. Experimental insights into the microphysics of molecule destruction and sputtering
Alexei V. Ivlev, Barbara M. Giuliano, Zoltán Juhász +12
We present a dedicated experimental study of microscopic mechanisms controlling radiolysis and sputtering of astrophysical ices due to their bombardment by cosmic ray ions. Such io…
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…
