The Last Gasps of a Dying Star: ALMA Observations of the Pre-Planetary Nebula IRAS 06530-0213
Raghvendra Sahai, Wouter Vlemmings, Guillermo Quintana-Lacaci +16
We present high angular-resolution () ALMA observations of millimeter-wave line and continuum emission (at and mm) in the pre-planetary ne…
SDSS-V Local Volume Mapper (LVM): Helix Nebula public data, Data Analysis Pipeline data products
S. F. Sánchez, J. E. Méndez-Delgado, A. Mejía-Narváez +21
We present a spatially resolved spectroscopic analysis of the Helix Nebula (NGC 7293) using data from the SDSS-V Local Volume Mapper (LVM), by applying the recently developed LVM D…
Appraising the Necklace: A post-common-envelope carbon dwarf inside an apparently carbon-poor planetary nebula
David Jones, Romano L. M. Corradi, Gustavo A. García Pérez +15
Context: The Necklace nebula is a bipolar, post-common-envelope planetary nebula, the central star of which has been shown to have a dwarf carbon star companion. Aims: We aim to un…
A morphological catalogue of Nova Remnants
Edgar Santamaria, Martin A. Guerrero, Gerardo Ramos-Larios +2
This work presents the first optical imaging catalogue of resolved Galactic nova remnants. It compiles images from proprietary observations carried out at the Nordic Optical Telesc…
Detailed Studies of IPHAS sources. II. Sab 19, a true planetary nebula and its mimic crossing the Perseus Arm
Martin A Guerrero, Roberto Ortiz, Laurence Sabin +2
The INT Photometric H Survey (IPHAS) has provided us with a number of new-emission line sources, among which planetary nebulae (PNe) constitute an important fraction. Here we pr…
Planetary nebulae with Wolf-Rayet-type central stars -- I. The case of the high-excitation NGC 2371
V. M. A. Gómez-González, J. A. Toalá, M. A. Guerrero +4
We present the analysis of the planetary nebula (PN) NGC 2371 around the [Wolf-Rayet] ([WR]) star WD 0722295. Our Isaac Newton Telescope (INT) Intermediate Dispersion Spectrogra…
