Kilometre-wave radio observations of solar type III bursts by Ulysses compared with decametre-wave observations from the Earth
Observations of solar type III bursts, made at kilometric frequencies by the radio receiver of the Ulysses Unified Radio and Plasma Wave (URAP) investigation, are compared with simultaneous observations, made at decametric frequencies at the Nançay Radio Astronomy Station of the ParisMeudonObservatory, during the period following the spacecraft encounter with Jupiter until the south solar polar...
متن کاملObservations of Type I Bursts from Neutron Stars
Observations of Type I X-ray bursts have long been taken as evidence that the sources are neutron stars. Black body models approximate the spectral data and imply a suddenly heated neutron star cooling over characteristic times of seconds to minutes. The phenomena are convincingly explained in terms of nuclear burning of accreted gas on neutron stars with low mass companion stars. Prospects are...
متن کاملCoronal type III radio bursts and their X-ray flare and interplanetary type III counterparts
Context. Type III bursts and hard X-rays are both produced by flare energetic electron beams. The link between both emissions has been investigated in many previous studies, but no statistical studies have compared both coronal and interplanetary type III bursts with X-ray flares. Aims. Using events where the coronal radio emission above 100 MHz is exclusively from type III bursts, we revisited...
متن کاملOBSERVATIONS Type III Allergy to Insulin Detemir
A llergy to insulin has become rare with human recombinant insulin or its analogs, with an estimated incidence of 1%. The most common clinical situation is related to the type I allergic reaction in the Gell and Coombs classification and usually consists of a local wheal-and-flare eruption at injection site with induration, pruritus, and burning sensation that appear a few minutes after the inj...
متن کاملA stochastic model for solar type III bursts
A stochastic model for type III bursts is introduced, discussed, and compared to observations. The active region is assumed to be inhomogeneous, with a large number of emerging magnetic fibers. At their bases, random energy release events take place, in the course of which electrons are accelerated, travel along the fibers and eventually undergo the bump-ontail instability. In the non-linear re...
