G5.89: An explosive outflow powered by a proto-stellar merger?
(Oxford University Press, 2019-06)
The explosive outflows are a newly discovered family of molecular outflows associated with high-mass star-forming regions. Such energetic events are possibly powered by the release of gravitational energy related with the ...
High-energy processes in starburst-driven winds
(Wiley Blackwell Publishing, Inc, 2020-08)
Starburst galaxies generate large-scale winds powered by the activity in the starforming regions located in the galactic disks. Fragmentation of the disk produced bythe outbreak of the wind results in the formation of ...
Discrepancies between the [O iii] and [S iii] temperatures in H ii regions
(EDP Sciences, 2012-06)
Context. Analysis of published [O iii] and [S iii] temperatures measurements of emission line objects consisting of Hii galaxies, giant extragalactic Hii regions, Galactic Hii regions, and Hii regions from the Magellanic ...
A nearby super-luminous supernova with a long pre-maximum & "plateau" and strong C II features
(EDP Sciences, 2018-12)
Context. Super-luminous supernovae (SLSNe) are rare events defined as being significantly more luminous than normal terminal stellar explosions. The source of the additional power needed to achieve such luminosities is ...
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 ...
Pulsating white dwarfs: new insights
(Springer, 2019-09-03)
Stars are extremely important astronomical objects that constitute the pillars on which the Universe is built, and as such, their study has gained increasing interest over the years. White dwarf stars are not the exception. ...
A large sub-Neptune transiting the thick-disk M4 v TOI-2406
(EDP Sciences, 2021-09)
Context. Large sub-Neptunes are uncommon around the coolest stars in the Galaxy and are rarer still around those that are metal-poor. However, owing to the large planet-to-star radius ratio, these planets are highly suitable ...
Pulsating low-mass white dwarfs in the frame of new evolutionary sequences: VI. Thin H-envelope sequences and asteroseismology of ELMV stars revisited
(EDP Sciences, 2018-12)
Context. Some low-mass white-dwarf (WD) stars with H atmospheres currently being detected in our galaxy, show long-period g(gravity)-mode pulsations, and comprise the class of pulsating WDs called extremely low-mass variable ...
