Possibility of Magnetic Mass Detection by the Next Generation of Microlensing Experiments
arXiv:astro-ph/0311242 · doi:10.1086/421728
Abstract
We study the possibility of magnetic mass detection by the gravitational microlensing technique. Recently the theoretical effect of magnetic mass in the NUT space on the microlensing light curve has been studied. It was shown that in the low photometric signal to noise and sampling rate of MACHO experiment light curves, no signature of NUT factor has been found. In order to increase the sensitivity of magnetic mass detection, we propose a systematic search for microlensing events, using the currently running alert systems and complementary telescopes for monitoring the Large Magellanic Clouds stars. In this strategy of observation, we obtain the magnetic mass detection efficiency and also the lowest observable limit of the NUT factor. This method of survey for gravitational microlensing detection can also be used as a tool for searching other exotic space-times.
