A strongly magnetic neutron star in a nearly face-on binary system
Article Abstract:
GRO J1744 - 24 is a neutron star near the Galactic Center that has a strong magnetic field, and produces temporary X-rays as intense bursts and periodical pulsations. The star has an X-ray spectrum similar to that of other neutron stars and an 11.8 day orbital period, and is a part of a binary star system. The dipole part of its magnetic field is less than or equivalent to 10 to the 11th power G. The maximum luminosity between X-ray bursts is nearly equal to the Eddington critical luminosity.

Stars arriving two by two
Article Abstract:
New observational data indicate that binary stars may occur more frequently among pre-main sequence stars than among older main sequence stars. This suggests that the coalescing of binary stars may be closely associated with the first stages of stellar evolution. Consequently, any theory intended to account for the origin of stars must now also explain why paired stars should be such a common feature of that origin in its early phases. In fact, as much as 65% of sun-like stars are binaries.

Growing up in a two-parent family?
Article Abstract:
The discovery of a circumstellar dust disk around the binary stars BD+31deg643 could shed valuable information on the late phases of planetary growth. The new disk differs from the previously discovered dust disk around Beta Pictoris since it orbits a pair of stars and has a dustier environment. The blue color of the disk, which contrasts sharply with the neutral color of the Beta Pic disk, is due to its smaller sized dust particles.
