... In 1930, Trumpler noticed that linear diameters (LD) of open clusters increase with distance (D) from the Sun. ... Since that time, the interstellar absorption has become one of the best studied factor in astrophysics, and we may hope that current OCL distance scales are free from this LD-D correlation. To verify if this is the case we have chosen several modern OCL distance scales and test them with the same clusters and the same angular diameters that Trumpler had used back in 1930. ...

As mentioned earlier, the transition of the rotator from the ejector state to the propeller state is not symmetrical. ... One can see that in the case of a fast rotator, an interval of appears where three different values of are possible, the upper value corresponding to the ejector state and the bottom value to the propeller state; the intermediate value is unstable. ...

Nova 1998 2 in M31 this image of the second Nova in M31 in 1998, was made from 38 exposures of 45 seconds integration time. It was made at September 21, 22h 20m UT. Telescope was a CG11 at f/6.3, no filters were used. The long list of processing steps caused the artefacts at the overexposed center of the galaxy and in many of the brighter stars. During the exposures thin clouds covered the sky but the CCD cuts through them, allowing me to obtain this result. ...

The perturbation method is based on the small-parameter expansion of an unknown solution of the light scattering problem in a vicinity of the exact solution. ... The only probably exclusion is the case of anisotropic particles for which the rigid solution is either impossible or too complicated. For such problems the perturbation method can give information of the first approximation, which is important for understanding of the basic principles of influences of the material anisotropy. ...

The rising tides. In 1777 Laplas made a report in the Paris academy about the rising tides and the falling tides. Their first model was considered by Newton and Kepler so that the rising tides and the falling tides were caused by the Moon and the Sun. This theory was developed by I. Bernully, Ailer and d'Alamber. Their scheme about the rising tides following on two directions (one to the Moon and the other to the Sun) was suited the non deep ocean in the stable planet. ...

. Comment on J1146-3328 . The derived position here is about 20" from that of the PMN survey position (Griffith & Wright 1993). The source is only detected on the shorter baselines and is probably resolved, although some smearing may be caused by the large position offset. VLBApls home page . Last modified: 16 Oct 2000
