WebAbstract. The UV Cet-type star flares and the chromospheric flares of the Sun have many important common features. Both types of events are very transient; they occupy only small parts of the stellar surfaces; in both cases the optical as well as the r)adio emission s of the flares have strong similarities in temporal and spectral characteristics.

Neutron stars are one result of massive star undergoing a core-collapse supernova. (If it is greater than a certain mass, the star will turn into a black hole instead.) They are very small, and very dense, and they emit radio pulses as they spin.
WebIt is shown that an adequate agreement of theory with the observations obtains regarding the internal regular features in the flare amplitude data inUBV rays, as well as the changes of the colour characteristics of stars during the flares; in the latter case the analysis is made not only in respect of the UV Cet-type stars, but flare stars as ...
