A differentiable and optimizable 3D model for interpretation of observed spectral data cubes
T. Grassi, J. E. Pineda, S. Spezzano +6
Molecular spectral cubes of prestellar cores encode the information on the physical and chemical properties of these objects along the line of sight. To retrieve this information,…
Hunting pre-stellar cores with APEX: overview
P. Caselli, S. Spezzano, E. Redaelli +8
[Abridged] Pre-stellar cores are centrally concentrated starless cores on the verge of star formation and they represent the initial conditions for star and planet forma…
Cosmic-ray ionisation rate in low-mass cores: the role of the environment
E. Redaelli, S. Bovino, G. Sabatini +6
Context: Cosmic rays drive several key processes for the chemistry and dynamical evolution of star-forming regions. Their effect is quantified mainly by means of the cosmic-ray ion…
Hunting pre-stellar cores with APEX: Corona Australis 151, the densest pre-stellar core or the youngest protostar?
E. Redaelli, S. Spezzano, P. Caselli +6
Context. Pre-stellar cores are the birthplaces of Sun-like stars and represent the initial conditions for the assembly of protoplanetary systems. Due to their short lifespans, they…
Hunting pre-stellar cores with APEX: IRAS16293E (Oph464)
S. Spezzano, E. Redaelli, P. Caselli +7
Pre-stellar cores are the first steps in the process of star and planet formation. However, the dynamical and chemical evolution of pre-stellar cores is still not well understood.…
