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.…
Time evolution of o-HD, ND, and NH during the high-mass star formation process
G. Sabatini, S. Bovino, E. Redaelli +5
Deuterium fractionation is a well-established evolutionary tracer in low-mass star formation, but its applicability to the high-mass regime remains an open question. The abundances…
AtLAST Science Overview Report
Mark Booth, Pamela Klaassen, Claudia Cicone +81
Submillimeter and millimeter wavelengths provide a unique view of the Universe, from the gas and dust that fills and surrounds galaxies to the chromosphere of our own Sun. Current…
Unveiling the role of magnetic fields in an accreting filament onto a young protocluster
Farideh S. Tabatabaei, Elena Redaelli, Daniele Galli +4
In order to develop a more comprehensive picture of star formation, it is essential to understand the physical relationship between dense cores and the filaments embedding them. Th…
A low cosmic-ray ionisation rate in the prestellar core Ophiuchus/H-MM1. Mapping of the molecular ions ortho-H2D+, N2H+, and DCO+
Jorma Harju, Charlotte Vastel, Olli Sipilae +5
(abridged) We have mapped the prestellar core H-MM1 in Ophiuchus in rotational lines of ortho-H2D+ (oH2D+), N2H+, and DCO+ at the wavelength 0.8 mm with the Large APEX sub-Millimet…
Fractionation in young cores: Direct determinations of nitrogen and carbon fractionation in HCN
S. S. Jensen, S. Spezzano, P. Caselli +4
We aim to determine the N/N and C/C ratios for HCN in six starless and prestellar cores and compare the results between the direct method using radiativ…
