Eclipsing Binaries in the Ogle Variable Star Catalog. Iv. the Pre-contact, Equal-mass Systems
We used the database of eclipsing binaries detected by the OGLE microlensing project in the pencil-beam search volume toward Baade’s Window to define a sample of 74 detached, equal-mass, main-sequence binary stars with short orbital periods in the range 0.19 < P < 8 days. The logarithmic slope of the period distribution, logN ∝ (−0.8 ± 0.2) log P , was used to infer the angular-momentum-loss (A...
متن کاملEclipsing Binaries in the OGLE Variable Star Catalog. III. Long-Period Contact Systems
A sample of contact binaries discovered by the OGLE project in Baade’s Window, with orbital periods longer than one day and with available color and light-curve data, has been analyzed. It consists of only 32 systems, in contrast to 388 W UMa-type systems with shorter periods which were analyzed before. Most systems are very distant and are probably located close to or in the galactic Bulge. Tw...
متن کاملA Multiwavelength Picture of the Afgl 5142 Star-forming Region
We present molecular line, H 2 O maser, radio continuum and near infrared maps of the bipolar outtow source AFGL 5142. The high resolution of our molecular CO observations enables us to deene the morphology of the large-scale bipolar outtow into a two lobe structure extending for 2 0 on each side of the center. In the perpendicular direction, we nd consistent evidence for a second, more compact...
متن کاملStar formation in M 33 : multiwavelength signatures across the disk
Aims. We use different tracers, such as Hα, ultraviolet (UV), and infrared (IR) emissions at various wavelengths, to study the dust and star-formation (SF) conditions throughout the disk of M 33. Methods. We derive the radial distribution of dust, of the old and young stellar population using Spitzer and GALEX data, complemented by ground-based optical data and available surveys of atomic and m...
