Chemical modeling of internal photon-dominated regions surrounding deeply embedded HC/UCHII regions
Gwendoline Stéphan, Peter Schilke, Jacques Le Bourlot +4
We aim to investigate the chemistry of internal photon-dominated regions surrounding deeply embedded hypercompact and ultracompact HII regions. We search for specific tracers of th…
Seeds of Life in Space (SOLIS). III. Zooming into the methanol peak of the pre-stellar core L1544
Anna Punanova, Paola Caselli, Siyi Feng +41
Towards the pre-stellar core L1544, the methanol (CHOH) emission forms an asymmetric ring around the core centre, where CHOH is mostly in solid form, with a clear peak 4000…
Seeds Of Life In Space (SOLIS): The organic composition diversity at 300--1000 au scale in Solar-type star forming regions
C. Ceccarelli, P. Caselli, F. Fontani +43
Complex organic molecules have been observed for decades in the interstellar medium. Some of them might be considered as small bricks of the macromolecules at the base of terrestri…
Seeds of Life in Space (SOLIS) III. Formamide in protostellar shocks: evidence for gas-phase formation
C. Codella, C. Ceccarelli, P. Caselli +47
Context: Modern versions of the Miller-Urey experiment claim that formamide (NHCHO) could be the starting point for the formation of metabolic and genetic macromolecules. Intri…
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…
Evolution of complex organic molecules in hot molecular cores: Synthetic spectra at (sub-)mm wavebands
Rumpa Choudhury, Peter Schilke, Gwendoline Stéphan +4
Hot molecular cores (HMCs) are intermediate stages of high-mass star formation and are also known for their rich emission line spectra at (sub-)mm wavebands. The observed spectral…
Variable circumstellar activity of V351 Orionis
Rumpa Choudhury, H. C. Bhatt, Gajendra Pandey
Context. Emission and absorption line profiles which are formed in the interaction of pre-main sequence (PMS) stars and their circumstellar environment are found to be variable at…
Triggered star formation and Young Stellar Population in Bright-Rimmed Cloud SFO 38
Rumpa Choudhury, Bhaswati Mookerjea, H. C. Bhatt
We have investigated the young stellar population in and around SFO 38, one of the massive globules located in the northern part of the Galactic HII region IC 1396, using the Spitz…
