RR Lyrae stars in the inner Large Magellanic Cloud: halo-like location with a disk-like distribution

Aims. The distribution of RR Lyrae stars (RRLS) in the inner Large Magellanic Cloud (LMC), and the structure of the halo of the LMC delineated by these stars are studied here. Methods. RRLS identified by the OGLE II survey are used to estimate their number density distribution in the bar region of the LMC. To find their location, I estimated the scale-height of their distribution in the LMC usi...

The distance modulus of the Large Magellanic Cloud based on double-mode RR Lyrae stars

We use double-mode RR Lyrae (RRd) stars from the macho variable star database of the Large Magellanic Cloud (LMC) to estimate its distance, by utilizing photometric data, linear pulsation and stellar atmosphere models. If we set EB−V = 0.11 and [M/H]= −1.5 for LMC, we get M − m = 18.52 mag, which is in agreement with the value obtained from Galactic cluster RRd stars. Although the formal statis...

Preliminary results for RR Lyrae stars and Classical Cepheids from the Vista Magellanic Cloud (VMC) Survey

The Vista Magellanic Cloud (VMC, PI M.R. Cioni) survey is collectingKS-band time series photometry of the system formed by the two Magellanic Clouds (MC) and the “bridge” that connects them. These data are used to build KS-band light curves of the MC RR Lyrae stars and Classical Cepheids and determine absolute distances and the 3D geometry of the whole system using the K-band period luminosity ...

The Macho Project Large Magellanic Cloud Variable Star Inventory. Xi. Frequency Analysis of the Fundamental Mode Rr Lyrae Stars

We have frequency analyzed 6391 variables classified earlier as fundamental mode RR Lyrae (RR0) stars in the macho database on the Large Magellanic Cloud (LMC). The overwhelming majority (i.e., 96%) of these variables have been proved to be indeed RR0 stars, whereas the remaining ones have fallen in one of the following categories: singleand double-mode Cepheids, binaries, first overtone and do...

The distance modulus of the Large Magellanic Cloud: Constraints from RR Lyrae pulsation properties

It has recently been suggested that the discrepancy between the “long” and “short” distance moduli of the Large Magellanic Cloud (LMC), as inferred from the properties of the Cepheid and RR Lyrae variables, respectively, might be due to the action of “third parameters” between the Galaxy and the LMC, which would make the RR Lyraes in the old LMC globular clusters brighter than their Galactic co...
