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…
Detection of Late-Time Circumstellar Interaction of SN 2017eaw in NGC 6946
Kathryn E. Weil, Robert A. Fesen, Daniel J. Patnaude +1
SN 2017eaw, the tenth supernova observed in NGC 6946, was a normal Type II-P supernova with an estimated 11 - 13 Msun supergiant progenitor. Here we present nebular phase spectra o…
Detection of the Red Supergiant Wind from the Progenitor of Cassiopeia A
Kathryn E. Weil, Robert A. Fesen, Daniel J. Patnaude +4
Cassiopeia A (Cas A) is one of the best studied young Galactic supernova remnants. While providing a rare opportunity to study in detail the remnant of a Type IIb supernova, questi…
Detection of Late-Time Optical Emission from SN 1941C in NGC 4136
Robert Fesen, Kathryn Weil
We report the detection of broad, high-velocity oxygen emission lines from the site of SN 1941C nearly eight decades after outburst, making it the oldest optically detected core-co…
New or Improved Orbital Periods of Cataclysmic Binaries
John R. Thorstensen, Frederick A. Ringwald, Cynthia J. Taylor +5
We present a table of 58 cataclysmic binary orbital periods determined using data from MDM Observatory. Most are heretofore unpublished; some are refinements of previously publishe…
