Nuclear spin ratios of deuterated ammonia in prestellar cores. LAsMA observations of H-MM1 and Oph D

Jorma Harju, Jaime E. Pineda, Olli Sipilä +6

We determine the ortho/para ratios of NH2D and NHD2 in two dense, starless cores, where their formation is supposed to be dominated by gas-phase reactions, which, in turn, is predi…

Initial conditions of star formation at $≲$ 2000 au: physical structure and NH $_{3}$ depletion of three early-stage cores

Yuxin Lin, Silvia Spezzano, Jaime E. Pineda +5

Pre-stellar cores represent a critical evolutionary phase in low-mass star formation. We aim to unveil the detailed thermal structure and density distribution of three early-stage…
