Protoplanetary Disks in the Orion Nebula: An H Fabry-Perot study and Astrobiological Aspects
Eduardo de la Fuente, Margarita Rosado, Lorena Arias +2
In this paper, we present a briefly overview of the protoplanetary disks in the Orion Nebula, incluiding some astrobiological aspects and an H Fabry-Perot study of 16 of them. W…
A Fabry-Perot Study of the Scd I galaxy NGC 5457
Ivanio Puerari, Margarita Valdez-Gutierrez, Margarita Rosado
We have analyzed Halpha Fabry-Perot interferograms of NGC 5457 (M101) in order to calculate the rotation curve. We have also isolated a sample of 263 HII regions and we determined…
Fabry-Perot Kinematics of HH 202, 203-204 in the Orion Nebula: Are they part of a Big Bipolar Outflow?
Margarita Rosado, Eduardo de la Fuente, Lorena Arias +1
We present a kinematic study of the Herbig-Haro objects HH 202, 203 and 204 using Halpha and [NII] Fabry-Perot velocity maps. For HH 202 we find new features that could belong to t…
The WC6 Wolf-Rayet star MLA 1159 in M31 and its ionization nebula BA 1-642
J. Greiner, G. H. Tovmassian, S. Komossa +2
We report on optical imaging and spectroscopic observations of the Wolf-Rayet candidate star MLA 1159 and the surrounding ionization nebula BA 1-642 in the Andromeda Galaxy. Though…
