Stellar populations in HII galaxies [PDF]
Proceedings of the International Astronomical Union, 2004 We analyse the stellar content of a large number of HII galaxies from the continua and absorption features of their spectra using population synthesis methods, in order to gain information about the star formation histories of these objects. We find that all galaxies of our sample contain an old stellar population (>= 1 Gyr) that dominates the ...

The Astrophysical Journal, 2008 The stellar content of M17 has been investigated by multicolor photometry and spectroscopy. Various independent estimates yield a distance of 2.1 ± 0.2 kpc. The ratio of total-to-selective extinction is R = 3.9. Within a projected area of 3.6 × 3.7 pc, there are several thousand stars.

Applications of Stellar Population Synthesis in the Distant Universe
Galaxies, 2020 Comparison with artificial galaxy models is essential for translating the incomplete and low signal-to-noise data we can obtain on astrophysical stellar populations to physical interpretations which describe their composition, physical properties ...

Intracluster Stellar Population [PDF]
Symposium - International Astronomical Union, 2004 I shall review the latest results for the presence of diffuse light in nearby clusters, and the evidence of ongoing star formation in an intracluster Virgo field. I shall discuss how intracluster planetary nebulae (ICPN) can be used as excellent tracers of the diffuse stellar population in nearby clusters.

Stellar population and kinematics of NGC 404 [PDF]
Astronomy and Astrophysics, 2010 NGC404 is a nearly face-on nearby low-luminosity lenticular galaxy. Probing its characteristics provides a wealth of information on the details of possible evolution processes of dS0 galaxies which may not be possible in other, more distant objects. In order to study its kinematics and star formation history, we obtained long slit spectroscopy at the ...

A study of stellar population of intermediate-age globular cluster NGC 2249
Results in Physics, 2020 The Large Magellanic Cloud (LMC) star cluster NGC 2249 has been found to exhibit an extended main-sequence turn-off (eMSTO) in the color-magnitude diagram (CMD) derived from the data of the Hubble Space Telescope (HST).

Abundances in Stellar Populations [PDF]
Symposium - International Astronomical Union, 1976 Stellar abundances are reviewed with emphasis on large-scale effects which may yield clues to galactic structure and evolution. Spectroscopic and indirect photoelectric abundance criteria are discussed, and utilized.The abundance statistics of nearby galactic disk stars, dominated by M dwarfs, but observed at spectral types F and GV and K III, suggest ...
