Astronomers Detect Coolest Radio Star . ... The new radio-star is much smaller and colder than our Sun.€а With a surface temperature not much higher than that of a giant planet, and a size comparable to JupiterтАЩs, it is scarcely visible in optical light.€а Yet the radio flares seen at Arecibo show it must have a strong magnetic field, implying that the same could be true of other similar stars. ...

In the first EGRET catalog, upper limits were given for selected objects not detected during the Phase 1 all-sky survey. These upper limits are determined using the likelihood calculation and depend on the EGRET exposure to a given direction, the contribution of the diffuse gamma radiation, and the proximity and strength of detected sources. ...
