The observers ’ view of ( very ) long X - ray bursts : they are super !
In many X-ray point sources on the sky, the X-ray emission arises because hydrogen and/or helium is accreted onto a neutron star from a nearby donor star. When this matter settles on the neutron star surface, it will undergo nuclear fusion. For a large range of physical parameters the fusion is unstable. The resulting thermonuclear explosions last from seconds to minutes. They are observed as s...
متن کاملRecurrent very - long type - I X - ray bursts in the low - mass X - ray binary 4 U 1636 – 53
Two flares with a duration of several hours are reported for the low-mass X-ray binary 4U 1636–53. The characteristics of these flares (i.e., decay time scales, spectral softening, fluences) are very similar to the very long type-I X-ray bursts recently found in several other low-mass X-ray binaries, suggesting that the flares in 4U 1636–53 are also very long type-I X-ray bursts. This would mak...
متن کاملA Unified Model of Short and Long Gamma-Ray Bursts, X-Ray Rich Gamma-Ray Bursts, and X-Ray Flashes
Taking into account the recent suggestion that a short gamma-ray burst (GRB) looks like the first 1 sec of a long GRB, we propose that the jet of a GRB consists of multiple sub-jets or sub-shells (i.e., an inhomogeneous jet model). The multiplicity of the sub-jets along a line of sight ns is an important parameter. If ns is large (≫ 1) the event looks like a long GRB, while if ns is small (∼ 1)...
متن کاملWhat Are Gamma-Ray Bursts? The Unique Role of Very High Energy Gamma-Ray Observations
Gamma-ray bursts (GRBs) have been an enigma since their discovery forty years ago. However, considerable progress unraveling their mysteries has been made in recent years. Developments in observations, theory, and instrumentation have prepared the way so that the next decade can be the one in which we finally answer the question, “What are gamma-ray bursts?” This question encompasses not only w...
