Next: Caverns in Binary Systems Up: Ejectors in Massive Binary Previous: The Number of Ejectors . In the very first years after the discovery of radiopulsars, it became clear that for some reason they avoid forming binary systems. ... Illarionov and Sunyaev (1975)[ 76 ] noted the fact that coherent radiowaves with a wavelength longer than 75 cm, which make it possible to observe most of the radiopulsars, are absorbed effectively in the stellar wind of a normal star. ...

... Ideally, this map contains the energy offset for each pixel (expressed in analog-to-digital units, adu). ... High-energy particles hitting the EPIC pn CCD during the offset map calculation may cause the affected pixels to get offset values which are incorrect by a few adu. ... Due to the specific method of deriving the offset map onboard, the affected areas occur often in blocks of four consecutive pixels along readout direction. ... The affected pixels usually get an offset which is too small. ...

Comets are small, fragile, irregularly shaped bodies composed of a mixture of non-volatile grains and frozen gases. ... Most become visible, even in telescopes, only when they get near enough to the Sun for the Sun's radiation to start subliming the volatile gases, which in turn blow away small bits of the solid material. ... Nearly 100 known comets have periods (the time it takes them to make one complete trip around the Sun) five to seven Earth years in length. ...

After being educated in Germany he returned to Russia and opened up a school for the deaf in St. Petersburg and later in Moscow, where he moved together with five of his pupils. ... In 1918 the school became state institute and was renamed into the Moscow Institute for the Deaf. ...

... Exposure Time Calculator (ETC) . Survey processing . ... VISTA is a 4-m class wide field survey telescope for the southern hemisphere, equipped with a near infrared camera (1.65 degree diameter field of view at VISTA's nominal pixel size) containing 67 million pixels of mean size 0.34 arcsec and available broad band filters at Z,Y,J,H,K s and a narrow band filter at 1.18 micron. A wide field visible camera, if constructed, could also be used on VISTA. ... Tile . ... ESO VISTA Public Surveys . ...

... In the context of the autonomous TAROT observatory we have developed an automatic scheduling software. ... With the advent of automatic telescopes and the use in service mode of large facilities, the problem of efficient night scheduling is becoming more important. ... However, we encountered some difficulties handling periodic or constrained requests with a large time interval, and it is unable to give to the telescope users and operators the visibility over the schedule. ...

Observation of the Sunyaev-Zel'dovich E ect toward CL0016+16 at 43 GHz M. Tsuboi et al. Ibaraki University, Japan We performed a mapping observation of the Sunyaev-Zel'dovich e ect toward a distant cluster of galaxies, CL0016+16, at 43 GHz using a newly developed 6-beam SIS receiver installed in the Nobeyama 45-m telescope. The temperature decrement of the cosmic microwave background radiation was measured to be
T  A = 0:490:05 mK at the central position of the cluster. ...

The preliminary ALFA pulsar surveys started on August 1st, 2004. In the first day of observations, a new 67.8-ms pulsar, PSR J1928+1746, was discovered: this was the first new pulsar found with ALFA. ... Strangely, the pulsar could not be detected in a 430-MHz observation. This pulsar's apparently unusual spectrum might not be so unusual: 1400-MHz surveys are biased towards finding this kind of object, but the pulsars found in these surveys were not consistently observed at higher frequencies. ...

Galaxy cluster Abell 2218 acts as a powerful lens, magnifying all galaxies lying behind the cluster core. The lensed galaxies are all stretched along the cluster's center and some of them are multiply imaged. ... The color of the lensed galaxies is a function of their distances and types. The orange arc is an elliptical galaxy at moderate redshift (z = 0.7). The blue arcs are star-forming galaxies at intermediate redshift (z = 1-2.5). ...

... In spite of the good potential possibilities, some of the station "Dnepr" design characteristics did not allow us to apply the usual special IS radar measurement methods. ... Thus for IS signal measurements at the "Dnepr" station, we have developed special methods for recording and processing IS signals in order to determine plasma ionospheric parameters. ...
