Photometric Solutions for Semi-Detached Eclipsing Binaries: Selection of Distance Indicators in the Small Magellanic Cloud

Estimation of distances to nearby galaxies by the use of eclipsing binaries as standard candles has recently become feasible because of new large scale instruments and the discovery of thousands of eclipsing binaries as spinoff from Galactic microlensing surveys. Published measurements of distances to detached eclipsing binaries in the Large Magellanic Cloud combine stellar surface areas (in ab...

The Star Clusters of the Small Magellanic Cloud: Structural Parameters

We present structural parameters for 204 stellar clusters in the Small Magellanic Cloud derived from fitting King and Elson, Fall, & Freeman model profiles to the V-band surface brightness profiles as measured from the Magellanic Clouds Photometric Survey images. Both King and EFF profiles are satisfactory fits to the majority of the profiles although King profiles are generally slightly superi...

The Distance to the Large Magellanic Cloud

A summary of recent Large Magellanic Cloud distance determinations μLMC is presented, with an eye towards pinpointing the source(s) of the resulting large discrepancies encountered between some of the techniques. Thirty-eight recent (1998-1999) measurements of μLMC are highlighted, the extrema for which (18.07 versus 18.74) are inconsistent with one another at the ∼ >3σ level. The lack of overl...

The Distance to the Large Magellanic Cloud

I demonstrate that the two unexpected results in the local Universe: anomalous intrinsic (V − I)0 colors of RR Lyrae stars and clump giants in the Galactic center, and very short distances to Magellanic Clouds inferred from clump giants, can be at least partially resolved with a modified coefficient of selective extinction AV /E(V − I). With this modification, I find a new clump-giant distance ...

Distance to the Large Magellanic Cloud

We remeasure the “light echo” times to the near and far side of the ring around SN 1987A using the method of Gould (1995) and the new reductions of the original UV spectra by Sonneborn et al. (1996). We obtain an upper limit to the distance to the Large Magellanic Cloud μLMC < 18.37 ± 0.04. This result is very close to Gould’s original value, and contradicts claims that the new spectra measurem...
