Rotation curves and dynamical masses of MaNGA barred galaxies
Eduardo O. Schmidt, Damián Mast, Gaia Gaspar +1
In this paper we analyse a sample of 46 barred galaxies of MaNGA. Our goal is to investigate the stellar kinematics of these galaxies and obtain their rotation curves. Additionally…
The determination of asteroid H and G phase function parameters using GAIA DR2
Milagros Colazo, Rene Duffard, Walter Weidmann
The Gaia mission will provide the scientific community with high-quality observations of asteroids of all categories. The second release of Gaia data (DR2) was published in 2018 an…
Catalogue of central stars of planetary nebulae: Expanded edition
W. A. Weidmann, M. B. Mari, E. O. Schmidt +7
Planetary nebulae represent a potential late stage of stellar evolution, however the central stars (CSPNe) are relatively faint and therefore pertinent information is merely availa…
Hunting white dwarfs at the center of planetary nebulae
Javier Ahumada, Walter Weidmann, Marcelo Miller Bertolami +1
We present Gemini-South observations of nine faint and extended planetary nebulae. Using direct images taken with the spectrograph GMOS, we built the vs. di…
Towards an improvement in the spectral description of central stars of planetary nebulae
W. Weidmann, R. Gamen, D. Mast +7
Context. There are more than 3000 known Galactic planetary nebulae (PNe), but only 492 central stars of Galactic planetary nebulae (CSPN) have known spectral types. It is vital to…
Asymmetric emission of the [OIII]5007 profile in narrow-line Seyfert 1 galaxies
Eduardo O. Schmidt, Gabriel A. Oio, Diego Ferreiro +2
Many active galactic nuclei (AGN) and particularly narrow-line Seyfert 1 (NLS1) galaxies, usually exhibit blueshifts and blue wings in several emission lines, which are mainly asso…
