cds-question@unistra.frchemical-abundancesgalaxy-clustersgalaxiesspectroscopyWe present line-strength measurements for 74 early-type galaxies in the core of the Coma cluster reaching down to velocity dispersions, {sigma}, of 30km/s. The index-{sigma} relations for our sample, including galaxies with {sigma}<100km/s (low-{sigma}), differ in shape depending on which index is used. We note two types of relations for the metallic indices: one showing a break in the slope around ~100km/s and another group with strong linear relations between an index and log {sigma}. We find no connection between the behavior of index-{sigma} relations with either {alpha}- or Fe-peak elements. However, we find indications that the relations are tighter for indices which do not depend on the microturbulent velocities of stellar atmospheres.2009ApJ...691.1862Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/691/1862CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/42 : GMP catalogue: galaxies in the Coma cluster (Godwin+ 1983)J/A+AS/116/429 : Classification of Coma early galaxies (Andreon+ 1996)J/A+AS/141/449 : Coma cluster early-type galaxies (Mehlert+, 2000)J/A+A/395/753 : Spectroscopy of Coma early-type galaxies.
