Data from the Fiber Optic Echelle Charge Coupled Device (CCD) Spectrograph at KPNO as well as IUE data were analyzed in this study of short period RS CVn and W UMa type binaries. A pulsar (from pulse and -ar as in quasar) is a highly magnetized rotating neutron star that emits beams of electromagnetic radiation out of its magnetic poles. This radiation can be observed only when a beam of emission is pointing toward Earth (much like the way a lighthouse can be seen only when the light is pointed in the direction of an observer), and is responsible for the pulsed.

The spectra of all require two emission components, evidenced by line emission characteristic of plasma at x K and bremsstrahlung characteristic of x K. We interpret the data in terms of magnetic coronal loops similar to those seen on.

The unusual intensity of the emission line spectrum makes this star unique among late-type dwarfs; emission line strengths bear comparison with those of T Tauri stars. HDE appears to be an intermediate object between premain sequence T Tauri stars and the main sequence flare and spotted stars.

The answers are A) specific to each different element and C) used to identify an unknown emission spectrum is the spectrum of frequencies of electromagnetic radiation. This radiation emitted due to the transition making from a high energy state to a lower energy state of an element. The later-type M dwarfs tend to have higher rotation, a larger percentage of them exhibit Hα emission, and they have strong fields. The increased visibility of Hα partly results from their cool photospheres, but there is an unexplained tendency for the Hα equivalent widths to remain relatively : Gibor Basri.   Coronal astronomy is by now a fairly mature discipline, with a quarter century having gone by since the detection of the first stellar X-ray coronal source (Capella), and having benefitted from a series of major orbiting observing facilities. Serveral observational characteristics of coronal X-ray and EUV emission have been solidly established through Cited by: Stellarium is a free GPL software which renders realistic skies in real time with OpenGL.
