... Based on the accurate radio position, GT 0236+610 was identified with LSI+61 303 (Gregory et al. , 1979[ 59 ]), a B0 star at a distance of 2 kpc (Frail and Hjellming, 1991[ 52 ]) with unusually broad, double-peaked, and variable and emission lines. ... The star wind velocity is estimated as  km s (Howarth, 1983[ 67 ]). ... The radio emission from LSI+61 303 exhibits non-thermal periodic outbursts of variable amplitude with a period of days (Taylor and Gregory, 1982, 1984[ 188 , 189 ]; Coe et al. ...

... Help the observer to classify the variables as classical Cepheids (C1), type II Cepheids (C2) and RR Lyrae stars (R). ... Notes: Classical Cepheid stars are a type of pulsating variable stars, which show linear relationship between period of pulsation and absolute luminosity in a log-log plot. ... RR Lyrae stars are another type of pulsating variable stars which show very short period (less than 1 day) of pulsation and for all RR Lyrae stars, the absolute luminosity is nearly constant. ...

... The main periodicity in the Sun 's activity is the 11-year cycle called the solar cycle. ... During the cycle, changes occur in the Sun's internal magnetic field and in the surface disturbance level. ... At the beginning of a cycle the solar magnetic field resembles a dipole which axis is aligned with Sun's rotation axis. ... The sunspot number - and Sun's activity - is at maximum in the middle of a cycle, when the Sun's internal magnetic field is most chaotic. ... Space Physics Text Book of Oulu ...

... Stars . ... Cepheid variable stars have been known since the 18th century. ... Regularly brightening to a peak over days, weeks or months before fading these variable stars were remarkable curiosities to astronomers in past centuries.€а The term Cepheid is taken from the star Delta Cephei in the constellation of Cepheus, which was identified as variable€а in 1784 by the teenaged prodigy John Goodricke (1764-96). ...
