We present 42 photoelectric minima observations of 24 eclipsing binaries.

We present the results of a 9.3-deg2 infrared (ZYJHK) survey in the Upper Scorpius association extracted from the UKIRT Infrared Deep Sky Survey (UKIDSS) Galactic Cluster Survey Early Data Release. We have selected a total of 112 candidates from the (Z - J,Z) colour-magnitude diagram over the Z = 12.5-20.5 magnitude range, corresponding to M = 0.25

We present the results of a near-infrared monitoring programme of a selected sample of stars, initially suspected to be Mira variables and OH/IR stars, covering more than a decade of observations. The objects monitored cover the typical range of IRAS colours shown by O-rich stars on the asymptotic giant branch and show a surprisingly large

The atmospheric parameters and iron abundance of the Sloan Digital Sky Survey (SDSS) spectrophotometric standard star BD +17 4708 are critically examined using up-to-date Kurucz model atmospheres, LTE line formation calculations, and reliable atomic data. We find Teff=6141 ± 50 K, log g=3.87 ± 0.08, and [Fe/H]=-1.74 ± 0.09. The line-of-sight

This paper reports on a near-infrared survey of early-type galaxies designed to provide information on bar strengths, bulges, disks, and bar parameters in a statistically well-defined sample of S0-Sa galaxies. Early-type galaxies have the advantage that their bars are relatively free of the effects of dust, star formation, and spiral structure that

The optical rest-frame sizes of 10 of the most massive (~5 × 1011h-270Msolar) galaxies found in the near-infrared MUNICS survey at 1.2 z 1.7 are analysed. Sizes are estimated in both the J and K' filters. These massive galaxies are at least a factor of 4+1.9-1.0 (+/-1σ) smaller in the rest-frame V-band than local counterparts of the same stellar
