Spectral energy distribution analysis of class i and class ii fu orionis stars
(IOP Publishing, 2014-06)
FU Orionis stars (FUors) are eruptive pre-main sequence objects thought to represent quasi-periodic or recurring stages of enhanced accretion during the low-mass star-forming process. We characterize the sample of known ...
Be star disc characteristics near the central object
(EDP Sciences, 2007-07)
Context. A recent analysis of visual Fell emission lines of 17 classic Be stars using the self-absorption curve (SAC) method revealed that these lines are optically thick and that they form in circumstellar disc (CD) regions ...
TOPoS II. On the bimodality of carbon abundance in CEMP stars Implications on the early chemical evolution of galaxies
(EDP SCIENCES S A, 2015)
Context. In the course of the Turn Off Primordial Stars (TOPoS) survey, aimed at discovering the lowest metallicity stars, we have found several carbon-enhanced metal-poor (CEMP) stars. These stars are very common among ...
Central star formation and metallicity in CALIFA interacting galaxies
(EDP Sciences, 2015)
We use optical integral-field spectroscopic (IFS) data from 103 nearby galaxies at different stages of the merging event, from close pairs to merger remnants provided by the CALIFA survey, to study the impact of the ...
Chemical signatures of formation processes in the stellar populations of simulated galaxies
(Oxford University Press, 2012-02)
We study the chemical properties of the stellar populations in eight simulations of the formation of Milky Way mass galaxies in a cold dark matter universe. Our simulations include metaldependent cooling and an explicitly ...
Scaled up low-mass star formation in massive star-forming cores in the G333 giant molecular cloud
(Oxford Univ Press, 2016)
Three bright molecular line sources in G333 have recently been shown to exhibit signatures of infall. We describe amolecular line radiative transfer (RT) modelling process which is required to extract the infall signature ...
