The Polarisation Signatures of Microlensing
نویسنده
چکیده
It has been shown by Simmons, Newsam & Willis (1995) (hereafter SNW95) that microlensing of stars can produce a distinctive and significant polarisation signature, even for lensed stars with no net unamplified polarisation. In this contribution, we use the model developed in SNW95 to simulate a series of realistic observations of microlensing events. We use these simulations to examine how much additional information about the parameters of the lensing event can be determined from polarisation measurements.

It has already been shown that microlensing can give rise to a non-zero variable polarisation signal. Here we use realistic simulations to demonstrate the additional information that can be gained from polarimetric observations of lensing events.
متن کاملThe polarisation signature from microlensing of circumstellar envelopes in caustic crossing events
In recent years it has been shown that microlensing is a powerful tool for examining the atmospheres of stars in the Galactic Bulge and Magellanic Clouds. 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 brightness profile of the source. Furthermore, models indicate that t...
متن کاملThe effect of variation of stellar dispersion velocities by the galactic latitude in interpreting gravitational microlensing observations
Our galaxy is a spiral galaxy and its stars are mostly in a thin disk and rotate around the galactic center. The vertical component of the dispersion velocity of stars is a function of the galactic latitude and decreases with increasing it. In the galactic Besancon model, this dependence is ignored and they just consider the dependence of dispersion velocity on the stellar age. Becanson model i...
متن کاملMicrolensing of circumstellar envelopes I. Simplified considerations for diagnosing radial and azimuthal flow
This paper presents first results on the line profile shapes from a circumstellar envelope in bulk motion as modified by a microlensing event. Only geometrically and optically thin spherical shells in uniform expansion or rotation are considered here so as to emphasise the information content available in the profile shapes. In particular it is demonstrated that for the case of expansion, the l...
متن کاملLetter to the Editor An ongoing parallax microlensing event OGLE-1999-CAR-1 toward Carina
We study the first microlensing event toward the Carina spiral arm discovered by the OGLE collaboration. We demonstrate that this long duration event exhibits strong parallax signatures. Additional information from the parallax effect allows us to determine the lens transverse velocity projected onto the Sun-source line to be ∼ 145 km s−1. We also estimate the optical depth, event rate and dura...
