Studying a precessing jet of a massive young stellar object within a chemically rich region
S. Paron, D. Mast, C. Fariña +4
In addition to the large surveys and catalogs of massive young stellar objects and outflows, dedicated studies of particular sources, in which high-angular observations (mainly at…
Studying a hot molecular core embedded in a photodissociation region
N. C. Martinez, M. B. Areal, S. Paron
At the first Galactic quadrant, at l=33.134, b=-0.091, an extended photodissociation region generated by an HII region complex lies. This region is related to abundant molecular ga…
Cyano radical emission at small spatial scales towards massive protostars
S. Paron, M. E. Ortega, A. Marinelli +2
The cyano radical (CN), one of the first detected interstellar molecular species, is a key molecule in many astrochemical chains. Particularly, it is detected towards molecular cor…
Studying the interstellar medium to look for relics of triggered star formation among stellar clusters
S. Paron, A. Granada, M. B. Areal
Evidence of triggered star formation at large spatial scales involving stellar clusters is scarce. We investigate a Galactic region (l=130.0, b=0.35) populated by several open stel…
Multiple molecular outflows and fragmentation in the IRDC core G34.43+00.24 MM1
N. L. Isequilla, M. E. Ortega, M. B. Areal +1
The fragmentation of a molecular cloud that leads to the formation of high-mass stars occurs on a hierarchy of different spatial scales. The large molecular clouds harbour massive…
Studying star-forming processes at core and clump scales: the case of the young stellar object G29.862-0.0044
M. B. Areal, S. Paron, C. Fariña +3
Massive molecular clumps fragment into cores where star formation takes place, hence star-forming studies should be done at different spatial scales. Using near-IR data obtained wi…
Three generations of stars: a possible case of triggered star formation
M. B. Areal, A. Buccino, S. Paron +2
Evidence for triggered star formation linking three generations of stars is difficult to assemble, as it requires convincingly associating evolved massive stars with Hii regions th…
Studying the molecular gas towards a bright rimmed cloud at the infrared dust bubble N30
A. Solernó, M. B. Areal, S. Paron
We present a study on the molecular gas towards a bright-rimmed cloud located to the north of the infrared dust bubble N30. Using the emission from the 12CO, 13CO, and C18O J=3-2 l…
Kinematic study of the molecular gas associated with two cometary globules in Sh2-236
M. E. Ortega, S. Paron, M. B. Areal +1
Cometary globules, dense molecular gas structures exposed to the UV radiation, are found inside HII regions. Understanding the nature and origin of these structures through a kinem…
Study of the 13CO/C18O abundance ratio towards the filamentary infrared dark cloud IRDC 34.43+0.24
M. B. Areal, S. Paron, M. E. Ortega +1
Nowadays there are several observational studies about the 13CO/C18O abundance ratio (X) towards nearby molecular clouds. These works give observational support to the C18O selecti…
Studying star-forming processes towards G29.862-0.044
M. B. Areal, S. Paron, M. E. Ortega +1
We present a multiwavelength study towards the young stellar object (YSO) G29.862-0.044 (hereafter G29), which is embedded in the massive star-forming region G29.96-0.02, located a…
Mapping the 13CO/C18O abundance ratio in the massive star forming region G29.96-0.02
S. Paron, M. B. Areal, M. E. Ortega
Estimating molecular abundances ratios from the direct measurement of the emission of the molecules towards a variety of interstellar environments is indeed very useful to advance…
Exploring the 13CO/C18O abundance ratio towards Galactic young stellar objects and HII regions
M. B. Areal, S. Paron, Peña M. Celis +1
Determining molecular abundance ratios is important not only for the study of the Galactic chemistry but also because they are useful to estimate physical parameters in a large var…
