Lambda Scorpii. The object is a bright and very compact astronomical radio source. The name Sagittarius A* distinguishes the compact source from the larger...

components is a compact object which is well within its Roche lobe, while the other is an evolved giant star. If the compact object is a white dwarf...

the object X is, in contrast to the fact that X need not be compact in C. Conversely, any compact object in Ind(C) arises as the image of an object in...

compact objects in question appear to have no solid surface, which can be deduced from the examination of X-ray bursts for which the central compact object...

these continue to evolve, with many companions eventually becoming compact objects such as white dwarfs or neutron stars themselves, though other possibilities...

long-standing puzzle surrounding type II supernovae is why the remaining compact object receives a large velocity away from the epicentre; pulsars, and thus...
