High-resolution spectroscopy of the bipolar proto-planetary nebula Hen 3-1475, the Garden Sprinkler Nebula
Ana Valeria Beltrán-Sánchez, Miriam Peña, Mudumba Parthasarathy
A detailed analysis of high-resolution spectra in the optical and near-infrared range of the central zone of the proto-planetary nebula Hen 3-1475, obtained in 2006 and 2024, is co…
The relation between the ADF and the ionized nebular mass in PNe
Miriam Peña, Fracisco Ruiz-Escobedo, Brenda N. Juárez Torres
In this work we analyze the proposed relation between ADFs and ionized masses in planetary nebulae. For this, we have collected from the literature the ADFs and other parameters su…
The extremely young planetary nebula M 3-27: an analysis of its evolution, physical conditions and abundances
Francisco Ruiz-Escobedo, Miriam Peña, Ana Valeria Beltrán-Sánchez
Spectrophotometric data of the young planetary nebula M 3-27, from 2004 to 2021, are presented and discussed. We corroborate that the H I Balmer lines present features indicating t…
Iron Depletion in ionized Nebulae of the Large Magellanic Cloud
G. Delgado-Inglada, M. Rodríguez, J. García-Rojas +2
We present here preliminary results of an analysis of the iron abundance in the ionized gas of three planetary nebulae and one H II region of the Large Magellanic Cloud (LMC). Thes…
