The path towards robust near-infrared extensions of stellar population models involves the confrontation between empirical and synthetic stellar spectral libraries across the wavelength ranges of photospheric emission. [...] With its near-UV to near-

In a previous paper, we assembled a collection of medium-resolution spectra of 35 carbon stars, covering optical and near-infrared wavelengths from 400 to 2400 nm. The sample includes stars from the Milky Way and the Magellanic Clouds, with a variety

Star formation histories and evolution of the 35 brightest E+A galaxies from the Sloan Digital Sky Survey Data Release 5

Autor: W. Du, A. L. Luo, Ph. Prugniel, Y. C. Liang, Y. H. Zhao

Publikováno v: Monthly Notices of the Royal Astronomical Society. 409:567-581

We pick out the 35 brightest galaxies from Goto's E+A galaxies catalogue which are selected from the Sloan Digital Sky Survey Data Release 5. As E+As have ex- perienced starburst recently and quenched it abruptly, they have been considered as post-st

Fitting whole spectra at intermediate spectral resolution (R = 1000 -- 3000), to derive physical properties of stellar populations, appears as an optimized alternative to methods based on spectrophotometric indices: it uses all the redundant informat

Kinematical data on early-type galaxies. VI

Autor: F. Simien, Ph. Prugniel

Publikováno v: Astronomy & Astrophysics. 384:371-382

We present the result of spectroscopic observations of a sample of 73 galaxies, completing the database published in this series of articles. The sample contains mostly low-luminosity early-type objects, including four dwarfs of the Local Group (in p

The formation of galaxy bulges: Spectrophotometric constraints

Autor: F. Simien, Ph. Prugniel, G. Maubon

Publikováno v: Astronomy & Astrophysics. 366:68-82

We have measured , Fe 5270 and Fe 5335 spectrophotometric indices (LICK system) in the bulge of 89 galaxies, mostly spirals from the Heraudeau ([CITE]) sample. The indices are reduced to a null velocity dispersion and normalized to an aperture of 0.2

This paper gives accurate coordinates and di- ameters for 3301 galaxies, companions of UGC galax- ies. (about 2764 companions were not yet available in electronic form). In addition previously poor equatorial coordinates are re-measured for 13823 gal

Kinematics of early-type galaxies in compact groups: HCG 67, HCG 74 and HCG 79

Autor: F. Simien, Ph. Prugniel, P. Bonfanti, Roberto Rampazzo

Publikováno v: International Astronomical Union Colloquium. 174:50-53

We present measurements of stellar kinematics for seven early-type galaxies in HCG 67, HCG 74 and HCG 79. These data are aimed at studying the relation between the environment and the dynamics, structure and stellar content of early-type galaxies. In

Using images of the Digitized Sky Survey we measured coodinates for 17298 galaxies having poorly de- ned coordinates. As a control, we measured with the same method 1522 galaxies having accurate coordinates. The comparison with our own measurements s
