Stellar winds of O-type stars traced by high ionization fine-structure emission lines with JWST/MIRI
Calum Hawcroft, David R. Law, Linda J. Smith +8
We investigate the presence of high ionization fine-structure emission lines across a range of 22 OB-type stars observed with JWST-MIRI as part of calibration programmes and the WI…
Modeling Forbidden Line Emission Profiles from Colliding Wind Binaries
R Ignace, R Bessey, C S Price
This paper presents calculations for forbidden emission line profile shapes arising from colliding wind binaries. The main application is for systems involving a Wolf-Rayet (WR) st…
The Effects of Clumps in Explaining X-ray Emission Lines from Hot Stars
J. P. Cassinelli, R. Ignace, W. L. Waldron +3
It is now well established that stellar winds of hot stars are fragmentary and that the X-ray emission from stellar winds has a strong contribution from shocks in winds. Chandra hi…
Constraints from ISO Data on the Velocity Law and Clumpiness of WR 136
R Ignace, M F Quigley, J P Cassinelli
Observations with the Infrared Space Observatory (ISO) SWS spectrometer are used to constrain the velocity law and wind clumping of the well-studied Wolf-Rayet (WR) star WR 136 (HD…
