چکیده

The MEGA microlensing survey is introduced and several topics about variable stars in M31 are discussed. An adopted model population of semiregular (SR) variable stars is presented, and the efficiency to recover these stars in M31 in a specific example MEGA dataset is predicted. The period-flux amplitude relation of the SRs discovered by MEGA could be used to measure the inclination of the M31 disk.

Pulsating red giant and supergiant stars in the Local Group dwarf galaxy Andromeda I

We have conducted an optical long-term monitoring survey of the majority of dwarf galaxies in the Local Group, with the Isaac Newton Telescope (INT), to identify the long period variable (LPV) stars. LPV stars vary on timescales of months to years, and reach the largest amplitudes of their brightness variations at optical wavelengths, due to the changing temperature. They trace stellar populati...

The second ROSAT PSPC survey of M31 and the complete ROSAT PSPC source list

This paper reports the results of the analysis of the second ROSAT PSPC survey of M31 performed in summer 1992. We compare our results with those of the first survey, already published in Supper et al. (1997). Within the ∼ 10.7 deg field of view, 396 individual X-ray sources are detected in the second survey data, of which 164 are new detections. When combined with the first survey, this result...

First microlensing candidate towards M31 from Nainital Microlensing Survey

We report our first microlensing candidate NMS-E1 towards M31 from the data accumulated during four years long Nainital Microlensing Survey. Cousin R and I band observations of ∼ 13 ′ × 13 ′ field in the direction of M31 were carried out since 1998 and data is analysed using pixel technique proposed by the AGAPE collaboration. The NMS-E1 lies in the disk of M31 at α = 04333.3 and δ = +41◦06 ′ 4...

Microlensing in M31 - The MEGA Survey’s Prospects and Initial Results

January 2000 completes the first season of intensive, widefield observations of microlensing and stellar variability in M31 by MEGA (“Microlensing Exploration of the Galaxy and Andromeda”) at the Isaac Newton 2.5m Telescope, the KPNO 4m, and the 1.3m and 2.5m telescopes of MDM Observatory. In preliminary analysis, we detect ∼50000 variable objects, including some consistent with microlensing ev...
