A Tale of Two Impostors: SN2002kg and SN1954J in NGC 2403
Roberta M. Humphreys, Kris Davidson, Schuyler D. Van Dyk +1
We describe new results on two supernova impostors in NGC 2403, SN 1954J(V12) and SN 2002kg(V37). For the famous object SN 1954J we combine four critical observations: its current…
Searching for Cool Dust: II. Infrared Imaging of the OH/IR Supergiants, NML Cyg, VX Sgr, S Per and the Normal Red Supergiants RS Per and T Per
Michael S. Gordon, Roberta M. Humphreys, Terry J. Jones +6
New MMT/MIRAC (9-11 μm), SOFIA/FORCAST (11-37 μm), and Herschel/PACS (70 and 160 μm) infrared (IR) imaging and photometry is presented for three famous OH/IR red supergiants (NML C…
Luminous and Variable Stars in M31 and M33 V. The Upper HR Diagram
Roberta M. Humphreys, Kris Davidson, David Hahn +2
We present HR Diagrams for the massive star populations in M31 and M33 including several different types of emission-line stars: the confirmed Luminous Blue Variables (LBVs), candi…
Multi-Epoch BVRI Photometry of Luminous Stars in M31 and M33
John C. Martin, Roberta M. Humphreys
We present the first four years of BVRI photometry from an on-going survey to annually monitor the photometric behavior of evolved luminous stars in M31 and M33. Photometry was mea…
