... Астрофизический практикум "Внутреннее строение звезд и звездная эволюция", для студентов 5 курса астрономического отделения физфака МГУ, призван дополнить курсы теоретической астрофизики и способствовать закреплению полученных в них знаний. ... Расчет эволюции звезд начинается с момента загорания водорода в ядре звезды на начальной главной последовательности, далее рассчитывается горение слоевого водородного источника, и превращение звезды в красного гиганта. ...
... The Solar TErrestrial RElations Observatory (STEREO) provides high cadence and high resolution images of the structure and morphology of coronal mass ejections (CMEs) in the inner heliosphere. ... MAGIC observations of MWC 656, the only known Be/BH system . ... The system has been associated with a gamma-ray flaring event detected by the AGILE satellite in July 2010. Aims: Our aim is to evaluate if the MWC 656 gamma-ray emission extends to very high energy (VHE > 100 GeV) gamma rays. ...
... We present a simple, effective technique that allows the contemporary spectroscopy of all the objects, up to a limiting magnitude, contained in a 100 arcmin 2 field. ... For this reason, we have developed a technique, that allows the simultaneous spectroscopy of all the objects included in a square field of view with 10 side, using the widely used FOSC-type optical spectrometer and camera focal-plane instruments. ... Thus the flux calibration of the slitless spectra was also straightforward. ...
