A large (~1 pc) contracting envelope around the prestellar core L1544
E. Redaelli, A. Chacón-Tanarro, P. Caselli +4
Prestellar cores, the birthplace of Sun-like stars, form from the fragmentation of the filamentary structure that composes molecular clouds, from which they must inherit at least p…
Transition from Coherent Cores to Surrounding Cloud in L1688
Spandan Choudhury, Jaime E. Pineda, Paola Caselli +8
Stars form in cold dense cores showing subsonic velocity dispersions. The parental molecular clouds display higher temperatures and supersonic velocity dispersions. The transition…
Relative Alignment between Dense Molecular Cores and Ambient Magnetic Field: The Synergy of Numerical Models and Observations
Che-Yu Chen, Erica A. Behrens, Jasmin E. Washington +26
The role played by magnetic field during star formation is an important topic in astrophysics. We investigate the correlation between the orientation of star-forming cores (as defi…
Seeds of Life in Space (SOLIS).VII. Discovery of a cold dense methanol blob toward the L1521F VeLLO system
C. Favre, C. Vastel, I. Jimenez-Serra +40
The SOLIS (Seeds Of Life In Space) IRAM/NOEMA Large Program aims at studying a set of crucial complex organic molecules in a sample of sources, with well-known physical structure,…
Seeds of Life in Space (SOLIS). VI. Chemical evolution of sulfuretted species along the outflows driven by the low-mass protostellar binary NGC1333-IRAS4A
Vianney Taquet, Claudio Codella, Marta de Simone +8
Context. Low-mass protostars drive powerful molecular outflows that can be observed with mm and sub-mm telescopes. Various sulfuretted species are known to be bright in shocks and…
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…
Droplets I: Pressure-Dominated Sub-0.1 pc Coherent Structures in L1688 and B18
Hope How-Huan Chen, Jaime E. Pineda, Alyssa A. Goodman +22
We present the observation and analysis of newly discovered coherent structures in the L1688 region of Ophiuchus and the B18 region of Taurus. Using data from the Green Bank Ammoni…
Mapping deuterated methanol toward L1544: I. Deuterium fraction and comparison with modeling
A. Chacon-Tanarro, P. Caselli, L. Bizzocchi +7
The study of deuteration in pre-stellar cores is important to understand the physical and chemical initial conditions in the process of star formation. In particular, observations…
The Green Bank Ammonia Survey: Unveiling the Dynamics of the Barnard 59 star-forming Clump
E. Redaelli, F. O. Alves, P. Caselli +17
Understanding the early stages of star formation is a research field of ongoing development, both theoretically and observationally. In this context, molecular data have been conti…
SOLIS II. Carbon-chain growth in the Solar-type protocluster OMC2-FIR4
F. Fontani, C. Ceccarelli, C. Favre +42
The interstellar delivery of carbon atoms locked into molecules might be one of the key ingredients for the emergence of life. Cyanopolyynes are carbon chains delimited at their tw…
