Intensive long-term photometric Q1 observations of the archetypical young G2 IIIe stellar object SU Aurigae are analyzed to determine many of its photometric and physical properties. Combining nearly 2000 Stromgren uvby measures obtained using the 0.

We have determined the distance to a second eclipsing binary (EB) system in the Large Magellanic Cloud, HV 982 (DB1 IVV ) DB1 IVV). The measurement of the distanceamong other properties of the systemis based on optical photometry and spectroscopy and

The long period (P = 27.1 yr) eclipsing binary є Aurigae (F0 Ia + disk?) is truly an exotic star. It has a deep eclipse that lasts for nearly two years. This eclipse arises as a huge, cool, flattened disk transits the F-supergiant star. Modeling of

OO Aql is a rare W UMa-type eclipsing binary in which the two solar-type stars may have only recently evolved into contact. The binary has an unusually high mass ratio (0.84), and a relatively long orbital period (0.506 d) for it spectral type (mid-G

We are carrying out an international, multi-wavelength program to determine the fundamental properties and independent distance estimates of selected eclipsing binaries in the LMC and SMC. Eclipsing binaries with well-defined double-line radial veloc

Multi‐wavelength studies of solar analogs (G0–G5 V stars) with ages from ∼50 Myr to 9 Gyr have been carried out as part of our ongoing Sun in Time program. These studies indicate that the young Sun was rotating over 10× faster than today. As a

The distance to the Large Magellanic Cloud (LMC) is crucial for the calibration of the Cosmic Distance Scale. We derive a distance to the LMC based on an analysis of ground-based photometry and HST-based spectroscopy and spectrophotometry of the LMC
