Star formation history, double degenerates and type Ia supernovae in the thin disc
stars: white dwarfs − stars: evolution − stars: binaries: close − supernovae: general − Galaxy: evolution − Galaxy: structure
2011/9/27
We investigate the relation between the star formation history and the evolution of the double-degenerate (DD) population in the thin disc of the Galaxy, which we assume to have formed 10 Gyr before t...
Dissecting high-mass star-forming regions; tracing back their complex formation history
Dissecting high-mass star-forming regions complex formation history
2011/8/24
We present near-infrared JHKs imaging as well as K-band multi-object spectroscopy of the massive stellar content of W3 Main using LUCI at the LBT. We confirm 13 OB stars by their absorption line spect...

The Origin of Dust in the Early Universe: Probing the Star Formation History of Galaxies by their Dust Content
galaxies evolution high-redshift starburst - quasars individ-ual
2010/11/11
Two distinct scenarios for the origin of the ∼ 4 × 108 M⊙ of dust observed in the high-redshift (z = 6.4) quasar J1148+5251 have been proposed. The first assumes that this galaxy is much younger...
The star formation history of the Large Magellanic Cloud as seen by star clusters and stars
galaxies evolution - galaxies: individual galaxies stellar content - galaxies star clusters
2010/11/10
The aim of this work is to test to what extent the star cluster population of a galaxy can be
utilised to constrain or estimate the star formation history, with the Large Magellanic Cloud as our test...
Spatially Resolved Star Formation History Along the Disk of M82 Using Multi-Band Photometric Data
galaxies individual (M82)– galaxies formation– galaxies star clusters
2010/11/12
We present the results on the star formation history and extinction in the disk of M82 over
spatial scales of 10′′ (180 pc). Multi-band photometric data covering from the far ultraviolet to the near...
The Star Formation History of Isolated Dwarf UGC4879
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/27
Recent observations of UGC4879 with the Advanced Camera for Surveys on the Hubble Space Telescope confirm that it is a nearby isolated dwarf irregular galaxy. We measure a distance of 1.36+/-0.03 Mpc ...
The Initial Mass Function and Young Brown Dwarf Candidates in NGC 2264. IV. The Initial Mass Function and Star Formation History
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/24
We have studied the star formation history and the initial mass function (IMF) using the age and mass derived from spectral energy distribution (SED) fitting and from color-magnitude diagrams. We also...
Cosmic star formation history revealed by the AKARI, & Spatially-resolved spectroscopy of an E+A (Post-starburst) system
