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…
Statistical nuclear spin ratios of deuterated ammonia in the pre-stellar core L1544
Jorma Harju, Paola Caselli, Olli Sipilae +6
We determined the ortho/para (o/p) ratios of NH2D and NHD2 in the archetypical pre-stellar core L1544. The core was observed in the two lowest rotational lines of ortho- and para-N…
Reexploring Molecular Complexity with ALMA: Insights into chemical differentiation from the molecular composition of hot cores in Sgr B2(N2)
A. Belloche, R. T. Garrod, H. S. P. Müller +3
We used ALMA to perform a line survey of the high-mass star forming region Sgr B2(N), called ReMoCA. We modeled under the assumption of LTE the spectra obtained toward the sources…
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…
Molecular inventory of a young eruptive star's environment -- Case study of the classical FU Orionis star V1057 Cyg
Zs. M. Szabó, A. Belloche, K. M. Menten +6
Studying accretion-driven episodic outbursts in YSOs is key to understanding the later stages of star and planet formation. FU Orionis-type objects form a YSO subclass, distinguish…
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.…
Exploring molecular complexity with ALMA (EMoCA): Complex isocyanides in Sgr B2(N)
E. R. Willis, R. T. Garrod, A. Belloche +4
We used the EMoCA survey data to search for isocyanides in Sgr B2(N2) and their corresponding cyanide analogs. We then used the coupled three-phase chemical kinetics code MAGICKAL…
