Microlensing of Circumstellar Envelopes. III. Line profiles from stellar winds in homologous expansion
M. A. Hendry, R. Ignace, H. M. Bryce
This paper examines line profile evolution due to the linear expansion of circumstellar material obsverved during a microlensing event. This work extends our previous papers on emi…
The polarisation signature from microlensing of circumstellar envelopes in caustic crossing events
R. Ignace, J. E. Bjorkman, H. M. Bryce
The high gradient of magnification across the source during both small impact parameter events and caustic crossings offers a unique opportunity for determining the surface brightn…
The microlensing signatures of starspots
M. A. Hendry, H. M. Bryce, D. Valls-Gabaud
Point lens microlensing events with impact parameter close to the source stellar radius allow the observer to study the surface brightness profile of the lensed source. We have exa…
Gravitational microlensing as a test of stellar model atmospheres
H. M. Bryce, M. A. Hendry, D. Valls-Gabaud
We present calculations illustrating the potential of gravitational microlensing to discriminate between classical models of stellar surface brightness profiles and the recently co…
Microlensing extended stellar sources
H M Bryce, M A Hendry
We have developed a code to compute multi-colour microlensing lightcurves for extended sources, including the effects of limb darkening and photospheric star spots as a function of…
