RESUMEN
Empleamos cuatro muestras limitadas en volumen de galaxias principales del Sloan Digital Sky Survey, versión 8 (SDSS DR8) para investigar la dependencia del medio ambiente de la tasa de formación estelar (SFR), la tasa específica de formación estelar (SSFR) y la masa en estrellas a una luminosidad fija. Aún fijando la luminosidad, se observa una fuerte dependencia ambiental de la SFR, la SSFR y de la masa en estrellas: las galaxias en la región de más baja densidad tienden a tener mayores SFR y SSFR, y masa en estrellas menores que las galaxias en la región de más alta densidad. Este resultado sugiere que al fijar la luminosidad no se altera apreciablemente la dependencia ambiental de la SFR, la SSFR y la masa en estrellas de las galaxias, lo cual muestra que la luminosidad no es un parámetro fundamental en las correlaciones entre las propiedades galácticas y el ambiente.
ABSTRACT
Using four volume-limited Main galaxy samples of the Sloan Digital Sky Survey Data Release 8 (SDSS DR8), we have investigated the environmental dependences of the SFR, SSFR and stellar mass at fixed luminosity. At fixed luminosity, we still observe strong environmental dependences of the SFR, SSFR and stellar mass of galaxies: galaxies in the lowest density regime preferentially have a higher SFR or SSFR and lower stellar mass than galaxies in the densest regime. This result suggests that the limitation or fixation of luminosity does not exert substantial influence on the environmental dependences of the SFR, SSFR and stellar mass of galaxies, which further shows that luminosity is not a fundamental parameter in correlations between galaxy properties and the environment.
Key Words: galaxies: fundamental parameters galaxies: statistics.
