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…
Discovery of a Fast Expanding Shell in the Inside-out Born-Again Planetary Nebula HuBi 1 Through High-Dispersion Integral Field Spectroscopy
J. S. Rechy-García, M. A. Guerrero, E. Santamaría +8
HuBi 1 has been proposed to be member of the rare class of born-again planetary nebulae (PNe), i.e., its central star experienced a very late thermal pulse and ejected highly-proce…
Detailed studies of IPHAS sources -- III. The highly extinguished bipolar planetary nebula IPHASX J191104.8060845
J. B. Rodríguez-González, L. Sabin, J. A. Toalá +6
We present the first detailed study of the bipolar planetary nebula (PN) IPHASX J191104.8060845 (PN G040.601.5) discovered as part of the Isaac Newton Telescope Photometric H…
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…
Rapidly-evolving episodic outflow in IRAS 18113-2503: clues to the ejection mechanism of the fastest water fountain
Gabor Orosz, Jose F. Gomez, Hiroshi Imai +11
Water fountains are evolved stars showing early stages of collimated mass loss during transition from the asymptotic giant branch, providing valuable insight into the formation of…
[WN] central stars of planetary nebulae
H. Todt, B. Miszalski, J. A. Toalá +1
While most of the low-mass stars stay hydrogen-rich on their surface throughout their evolution, a considerable fraction of white dwarfs as well as central stars of planetary nebul…
A search for water maser emission toward obscured post-AGB star and planetary nebula candidates
J. F. Gomez, J. R. Rizzo, O. Suarez +5
Water maser emission at 22 GHz is a useful probe to study the transition between the nearly spherical mass-loss in the AGB to a collimated one in the post-AGB phase. In their turn,…
WISE morphological study of Wolf-Rayet nebulae
J. A. Toalá, M. A. Guerrero, G. Ramos-Larios +1
We present a morphological study of nebulae around Wolf-Rayet (WR) stars using archival narrow-band optical and Wide-field Infrared Survey Explorer (WISE) infrared images. The comp…
Absence of hot gas within the Wolft-Rayet Bubble around WR16
J. A. Toalá, M. A. Guerrero
We present the analysis of XMM-Newton archival observations towards the Wolf-Rayet (WR) bubble around WR16. Despite the closed bubble morphology of this WR nebula, the XMM-Newton o…
Variable dust formation by the colliding-wind Wolf-Rayet system HD 36402 in the Large Magellanic Cloud
P. M. Williams, Y. -H. Chu, R. A. Gruendl +1
Infrared photometry of the probable triple WC4(+O?)+O8I: Wolf-Rayet system HD 36402 (= BAT99-38) in the Large Magellanic Cloud (LMC) shows emission characteristic of heated dust. T…
Discovery of X-ray emission from young suns in the Small Magellanic Cloud
L. M. Oskinova, W. Sun, C. J. Evans +11
We report the discovery of extended X-ray emission within the young star cluster NGC 602 in the Wing of the Small Magellanic Cloud (SMC) based on observations obtained with the Cha…
The slow X-ray pulsar SXP 1062 and associated supernova remnant in the Wing of the Small Magellanic Cloud
L. M. Oskinova, M. A. Guerrero, V. Henault-Brunet +6
SXP 1062 is an exceptional case of a young neutron star in a wind-fed high-mass X-ray binary associated with a supernova remnant. A unique combination of measured spin period, its…
Discovery of a Be/X-ray pulsar binary and associated supernova remnant in the Wing of the SMC
V. Hénault-Brunet, L. M. Oskinova, M. A. Guerrero +6
We report on a new Be/X-ray pulsar binary located in the Wing of the Small Magellanic Cloud (SMC). The strong pulsed X-ray source was discovered with the Chandra and XMM-Newton X-r…
