Stellar longitudinal magnetic field determination through multi-Zeeman signatures
J. C. Ramírez Vélez, M. J. Stift, S. G. Navarro +3
Context. A lot of effort has been put into the detection and determination of stellar magnetic fields using the spectral signal obtained from the combination of hundreds or thousan…
Variation Of The Tully-Fisher Relation As A Function Of The Magnitude Interval Of A Sample Of Galaxies
A. Ruelas-Mayorga, L. J. Sánchez, M. Trujillo-Lara +4
In this paper we carry out a preliminary study of the dependence of the Tully-Fisher Relation (TFR) with the width and intensity level of the absolute magnitude interval of a limit…
Dark matter inside early-type galaxies as function of mass and redshift
A. Nigoche-Netro, G. Ramos-Larios, P. Lagos +6
We study the behaviour of the dynamical and stellar mass inside the effective radius (re) of early-type galaxies (ETGs). We use several samples of ETGs -ranging from 19 000 to 98 0…
CCD photometry of the Globular Cluster NGC 6093
A. Ruelas-Mayorga, L. J. Sanchez, C. A. Bernal-Herrera +3
In this paper we present photometric CCD observations of the globular cluster NGC 6093 (M80) in filters B, V , R and I. We produce the colour-magnitude diagrams for this object and…
