Optical Discovery of New and Candidate Galactic Supernova Remnants Plus Optical Imaging of the Monogem Supernova Remnant
Robert A. Fesen, Marcel Drechsler, Bray Falls +16
We report the discovery of new and candidate Galactic supernova remnants made through over 2000 hours of H and [O III] imaging using amateur class instrumentation. These nebulae…
The Ejecta Nebula Around the Wolf-Rayet Star WR 71
Robert A. Fesen, Manuel C. Peitsch, Martin R. Pugh +2
We present deep H and [O III] images of the ejecta rich nebulosity associated with the suspected runaway and binary Wolf-Rayet star WR~71 (HD 143414). In H emission, the nebu…
SDSO1 is a Shocked Ghost Planetary Nebula in Front of M 31
Patrick Ogle, Mark Petersen, R. Michael Rich +12
We present new, deep narrowband imagery and discuss the nature of SDSO 1, the large [O III]-emitting nebula centered 1.5 degrees SE of M 31. We find strong evidence to support the…
Discovery of a [O III] Emission Shell Around the X-ray Binary CI Cam
Robert A. Fesen, Marcel Drechsler, Nicolas Martino +1
We report the serendipitous discovery of a emission shell brightest in [O III] centered on the X-ray binary B[e] star, CI Cameleopardalis (CI Cam). This shell, dete…
Deep Optical Emission-Line Images of Nine Known and Three New Galactic Supernova Remnants
Robert A. Fesen, Marcel Drechsler, Xavier Strottner +14
Deep optical emission-line images are presented for nine known plus three new Galactic supernova remnants (SNRs), all but one having at least one angular dimension greater than one…
Extended far-UV emission surrounding asymptotic giant branch stars as seen by GALEX
V. Răstău, M. Mečina, F. Kerschbaum +5
Aims. Our goal is to study the long-term mass-loss rate characteristics of asymptotic giant branch (AGB) stars through wind-wind and wind-interstellar medium interaction. Methods.…
The Spatial and Emission Properties of the Large [O III] Emission Nebula Near M31
Robert A. Fesen, Stefan Kimeswenger, J. Michael Shull +8
Drechsler et al. (2023) reported the unexpected discovery of a 1.5 degree long [O III] emission nebula 1.2 degrees southeast of the M31 nucleus. Here we present additional images o…
YY Hya and its interstellar environment
Stefan Kimeswenger, John R. Thorstensen, Robert A. Fesen +7
During a search for previously unknown Galactic emission nebulae, we discovered a faint 36' diameter Halpha emission nebula centered around the periodic variable YY Hya. Although t…
Far UV and Optical Emissions from Three Very Large Supernova Remnants Located at Unusually High Galactic Latitudes
Robert A. Fesen, Marcel Drechsler, Kathryn E. Weil +9
Galactic supernova remnants (SNRs) with angular dimensions greater than a few degrees are relatively rare, as are remnants located more than ten degrees off the Galactic plane. Her…
G107.0+9.0: A New Large Optically Bright, Radio and X-Ray Faint Galactic Supernova Remnant in Cepheus
Robert A. Fesen, Kathryn E. Weil, John C. Raymond +7
Wide-field H-alpha images of the Galactic plane have revealed a new supernova remnant (SNR) nearly three degrees in diameter centred at l = 107.0, b = +9.0. Deep and higher resolut…
