The first steps of Interstellar Phosphorus Chemistry
Johanna Chantzos, Victor M. Rivilla, Anton Vasyunin +4
Phosphorus-bearing species are an essential key to form life on Earth, however they have barely been detected in the interstellar medium. Since only PN and PO have been identified…
Collisional excitation of NH(3Σ-) by Ar: A new ab initio 3D potential energy surface and scattering calculations
D. Prudenzano, F. Lique, R. Ramachandran +2
Collisional excitation of light hydrides is important to fully understand the complex chemical and physical processes of atmospheric and astrophysical environments. Here, we focus…
Why does ammonia not freeze out in the center of pre-stellar cores?
O. Sipilä, P. Caselli, E. Redaelli +2
We carried out a parameter-space exploration of the ammonia abundance in the pre-stellar core L1544, where it has been observed to increase toward the center of the core with no si…
First interferometric study of enhanced N-fractionation in NH: the high-mass star-forming region IRAS 05358+3543
L. Colzi, F. Fontani, P. Caselli +3
Nitrogen (N) fractionation is used as a tool to search for a link between the chemical history of the Solar System and star-forming regions. A large variation of N/N…
Efficient methanol production on the dark side of a prestellar core
Jorma Harju, Jaime E. Pineda, Anton I. Vasyunin +23
We present ALMA maps of the starless molecular cloud core Ophiuchus/H-MM1 in the lines of deuterated ammonia (ortho-NH2D), methanol (CH3OH), and sulphur monoxide (SO). The dense co…
Dust opacity variations in the pre-stellar core L1544
A. Chacon-Tanarro, J. E. Pineda, P. Caselli +13
Context: The study of dust emission at millimeter wavelengths is important to shed light on the dust properties and physical structure of pre-stellar cores, the initial conditions…
