A consistent explanation for C/C, Li, and He anomalies in red giant stars
Corinne Charbonnel
The observations of carbon isotopic ratios in evolved stars suggest that non standard mixing is acting in low mass stars as they are ascending the red giant branch. We propose a si…
Morphological classification and structural parameters for early-type galaxies in the Coma cluster
S. Andreon, E. Davoust, R. Michard +2
We present the results of an isophotal shape analysis of three samples of galaxies in the Coma cluster. Quantitative morphology, together with structural and photometric parameters…
Pure Luminosity Evolution Hypothesis for QSOs: From Luminosity Functions to Synthetic Catalogues
G. Mathez, L. Van Waerbeke, Y. Mellier +2
This paper describes the simulation of realistic Monte-Carlo extragalactic catalogues, aimed at comparing the behaviour of cosmological tests versus input parameters. QSO catalogue…
The purpose of astronomy
Emmanuel Davoust
This is a presentation of the purpose of astronomy in the context of modern society. After exposing two misconceptions about astronomy, I detail its role in five domains, certified…
Software for producing trichromatic images in astronomy
Sebastien Morel, Emmanuel Davoust
We present a software package for combining three monochromatic images of an astronomical object into a trichromatic color image. We first discuss the meaning of "true" colors in a…
Starbursts in barred spiral galaxies. I. Mrk 712: a new Wolf-Rayet galaxy
Thierry Contini, Emmanuel Davoust, Suzanne Considere
We report the discovery of emission from Wolf-Rayet stars in a giant HII region 4.5 arcsec South of the nucleus of the IRAS barred spiral galaxy Mrk 712. The ratio of WNL to OV sta…
