A B-type main-sequence star (B V) is a main-sequence (hydrogen-burning) star of spectral type B and luminosity class V. These stars have from 2 to 16 times the mass of the Sun and surface temperatures between 10,000 and 30,000 K. [1]
The team released a paper of their findings dated 27 April 2007, published in the July 2007 journal Astronomy & Astrophysics. [1] At the time of discovery, it was reported to be the first potentially Earth-like planet in the habitable zone of its star [5] [6] and the smallest-known exoplanet around a main-sequence star, but on 21 April 2009, another planet orbiting Gliese 581, Gliese 581e ...
Powerful laser guide star system at the Paranal Observatory. The actual laser guide star is the small spot above the apparent end of the laser beam. A laser guide star is an artificial star image created for use in astronomical adaptive optics systems, which are employed in large telescopes in order to correct atmospheric distortion of light (called astronomical seeing).
Bintang invested US$1 billion [4] in a partnership with Tsingshan Holding Group to build Indonesia Morowali Industrial Park (IMIP) nickel processing facility in Central Sulawesi [5] which opened in 2015. [6] [7] IMIP employs 30,000 people and operates 20 smelters. [5] As of 2022, Bintang was a 33.75% shareholder in IMIP. [1]
