We present a study of the kinematics of the isolated spiral galaxy NGC 864, using Hα Fabry-Perot data obtained with the Galaxy Hα Fabry-Perot System (GHαFaS)...
Hα kinematics of S4G spiral galaxies - II. Data description and non-circular motions
We present a kinematical study of 29 spiral galaxies included in the Spitzer Survey of Stellar Structure in Galaxies, using Hα Fabry-Perot (FP) data obtained...
Hα kinematics of S4G spiral galaxies - III. Inner rotation curves
We present a detailed study of the shape of the innermost part of the rotation curves of a sample of 29 nearby spiral galaxies, based on high angular and...
Hα kinematics of the Spitzer Infrared Nearby Galaxies Survey - II
This is the second part of an Hα kinematics follow-up survey of the Spitzer Infrared Nearby Galaxies Survey (SINGS) sample. The aim of this paper is to shed new...
Hα line profiles for a sample of supergiant HII regions. I. The main spectral component
We present an analysis of the Hα emission line profiles of a sample of giant extragalactic HII regions, selected from among the brightest and most isolated in a...
Hα line profiles for a sample of supergiant HII regions. II. Broad, low intensity components
We analyze the broad, low intensity, high velocity components that are seen in the Hα line profiles for a sample of HII regions. These HII regions are chosen...
We carried out optical and Hα photometry of two contact binaries (V861 Herculis, EQ Tauri). The light curve modeling revealed stellar spots in both contact...
Hα spectropolarimetry of RY Tauri and PX Vulpeculae
Aims: To detect line effects using spectropolarimetry in order to find evidence of rotating disks and their respective symmetry axes in T Tauri stars. Methods...
Hα spectropolarimetry of the B[e] supergiant GG Carinae
Aims. We study the geometry of the circumstellar environment of the B[e] supergiant star GG Car. Methods: We present observations acquired using the IAGPOL...
