Three generations of stars: A possible case of triggered star formation
(Wiley Blackwell Publishing, Inc, 2020-06)
Evidence for triggered star formation linking three generations of stars is difficult to assemble, as it requires convincingly associating evolved massive stars with H ii regions that, in turn, would need to present signs ...
The VMC Survey. XXII. Hierarchical Star Formation in the 30 Doradus-N158-N159-N160 Star-forming Complex
(IOP Publishing, 2017-02)
We study the hierarchical stellar structures in a ∼1.5 deg2 area covering the 30 Doradus-N158-N159-N160 star-forming complex with the VISTA Survey of Magellanic Clouds. Based on the young upper main-sequence stars, we find ...
Hierarchical star formation in nearby galaxies
(EDP Sciences, 2020-10)
Aims. The purpose of this work is to study the properties of the spatial distribution of the young population in three nearby galaxiesin order to better understand the first stages of star formation.Methods. We used ACS/HST ...
Identification and analysis of the young population in the starburst galaxy NGC 253
(Wiley Blackwell Publishing, Inc, 2018-07)
We present a study of the young population in the starburst galaxy NGC 253. In particular, we focused our attention on searching young star groups, obtaining their main properties and studying their hierarchical organization. ...
γ-ray/infrared luminosity correlation of star-forming galaxies
(EDP Sciences, 2020-09)
Context. Nearly a dozen star-forming galaxies have been detected in γ-rays by the Fermi observatory in the last decade. A remarkable property of this sample is the quasi-linear relation between the γ-ray luminosity and the ...
On the formation of hydrogen-deficient low-mass white dwarfs
(EDP Sciences, 2020-06)
Context. Two of the possible channels for the formation of low-mass (M∗≲ 0.5 M· ) hydrogen-deficient white dwarfs are the occurrence of a very-late thermal pulse after the asymptotic giant-branch phase or a late helium-flash ...
Identifying the formation mechanism of redback pulsars
(Oxford University Press, 2020-04)
We analyse the evolution of close binary systems containing a neutron star that lead to the formation of redback pulsars. Recently, there has been some debate on the origin of such systems and the formation mechanism of ...
Detailed photometric analysis of young star groups in the galaxy NGC 300
(EDP Sciences, 2016-10)
Aims: The purpose of this work is to understand the global characteristics of the stellar populations in NGC 300. In particular, we focused our attention on searching young star groups and study their hierarchical organization. ...
On the incidence of chemically peculiar stars in the Large Magellanic Cloud
(Oxford University Press, 2005-09)
With the aim to corroborate the result of a search for chemically peculiar stars in the Large Magellanic Cloud (LMC), we present measurements obtained from CCD imaging of two fields, one containing a young open cluster ...
Distribution of Serpens South protostars revealed with ALMA
(EDP Sciences, 2018-07)
Context. Clusters are common sites of star formation, whose members display varying degrees of mass segregation. The cause may be primordial or dynamical, or a combination both. If mass segregation were to be observed in ...
