Optical Spectroscopy of a Candidate O-Star X-ray Binary in M33
Margaret Lazzarini, Lara Cullinane, Karoline Gilbert +8
We present new observations of a candidate O-type donor star in a high mass X-ray binary (HMXB) in M33. The candidate donor star is spatially coincident with a hard X-ray point sou…

Multiwavelength Characterization of the High Mass X-ray Binary Population of M33
Margaret Lazzarini, Kyros Hinton, Cheyanne Shariat +12
We present multi-wavelength characterization of 65 high mass X-ray binary (HMXB) candidates in M33. We use the Chandra ACIS survey of M33 (ChASeM33) catalog to select hard X-ray po…
