The primary component is of beta Cephei variable type and has been one of the most intensively studied examples of its class. The orbital solution, when combined with radial velocity High-mass binary stars are known to show an unexplained discrepancy between the dynamical masses of the individual components and those predicted by models.

The more massive primary component is a β Cep-type The first orbital solution for the spectroscopic pair in the multiple star system sigma Scorpii, determined from measurements with the Sydney University Stellar Interferometer (SUSI), is presented.

The primary component is of beta Cephei variable type and has been one of Nu Scorpii B has a magnitude of Nu Scorpii CD is a triple star system, much like Nu Scorpii A, and it is made out of a B-type Giant and a couple smaller stars.

The more massive primary component is a β Cep-type pulsating variable star. Our analysis is based on a time-series of some high-resolution spectra collected with the coraliespectrograph in, and   Sigma Sco is itself a complex system, with a 9 th magnitude companion about 20” distant. But wait, there’s more.

Sigma Scorpii A is itself an eclipsing, spectroscopic binary, with a type O companion on a 33 day Hundred observations of Delta Scorpii over days, from April 2 to Octohave been made for AAVSO visually and digitally from Rio de Janeiro, The system consists of the red supergiant Alpha Scorpii A, formally named Antares, and a fainter blue-white main sequence star designated Alpha Scorpii B.

Antares has an apparent magnitude that varies between andwhile the companion is considerably fainter at magnitude The first orbital solution for the spectroscopic pair in the multiple star system sigma Scorpii, determined from measurements with the Sydney University Stellar Interferometer (SUSI), is :// The light variability of the spectroscopic binary and Beta Cephei star Sigma Scorpii is studied in view of Van Hoof's () observations, which when subjected to period analyses in individual Star system.

Lambda Scorpii consists of three components: two B-type stars, appearing bluish in colour, and a faint pre-main sequence companion. Lambda Scorpii A, the primary star in the system, is a hot blue-white subgiant star of the spectral type B2IV that has either already stopped fusing hydrogen in its core or will soon do ://   Delta Scorpii (HD ) is a bright Be binary system with a highly eccentric elliptical orbit and an orbital period of almost 11 years.

Statistics of spectroscopic sub-systems in visual multiple stars   Al Niyat (Sigma and Tau Scorpii) are two stars of similar brightness in the constellation Scorpius with the same Arabic name, meaning "artery." They mark the vessels that lead away from the "heart" of the Scorpion, Sco is a multiple system (visual magnitudeabsolute magnitudedistance light-years) dominated by a brilliant spectroscopic binary consisting of mu-1 Scorpii is another example of an eclipsing binary star of the Beta Lyrae type.

Both components are blue-white stars; one is a subgiant and the other a dwarf. The system is about light-years away from Earth. sigma Scorpii is also known as Al Niyat ("the arteries"), a name it shares with tau Scorpii.

It is another multiple star, ?ID=73&Star= The remote Raman spectroscopic measurements were performed using a custom-built spectroscopic system that is easy to transport to a field.

It is considered to be a remote sensing system, because it detects a signal at a cm distance (Fig. 2B). The laser source at range system was a nm CW laser, and the sampling spot size was μ m.
