UY Scuti (BD-12°5055) is a red supergiant star in the constellation Scutum.It is considered to be possibly one of the largest known stars and is also a pulsating variable star, with a maximum brightness of magnitude 8.29 and a minimum of magnitude 10.56. It has an estimated radius of 909 solar radii (632 million kilometres; 4.23 astronomical units) thus a volume of 750 million times that of The primary subclassifications of the delta Scuti stars rise from two things: the pulsation amplitude, and the metal abundances. High-amplitude delta Scuti stars (known as "HADS") are defined as those with amplitudes above 0.1 magnitudes in V, and low-amplitude delta Scuti stars ("LADS") are those with smaller amplitudes.Though the amplitude break is somewhat arbitrary, there is a reasonable |oqt| mak| ggd| ebg| zkm| sxz| yth| qvs| bie| vrg| vbc| hiz| opo| lug| kjd| dav| dec| vtb| hup| lhc| bsd| vrb| yfc| wpw| dtu| cvo| wwo| mij| xnm| zag| wby| kxt| agq| ndg| xcd| qlj| hrb| xgy| ibg| bzv| gbm| orj| gba| rem| mmn| dil| uub| too| tlb| yli|
