The star is similar to the Sun, with about 0.93 M ☉ and 0.99 R ☉, and a temperature of about 5,850 K (5,580 °C; 10,070 °F), while the black hole has a mass of about 9.62 M ☉. [3] Given this mass, the black hole's Schwarzschild radius should be about 28 km (17 mi).
BH Radio 1 is a Bosnian national public mainstream radio channel operated by Radio and Television of Bosnia and Herzegovina (BHRT). The program is broadcast on a daily basis 24 hours with equal use one of the three official languages in Bosnia and Herzegovina (Bosnian, Croatian or Serbian). This radio station broadcasts a variety of programs ...
The construction of Terminal 2 - an extension of Terminal 1 - started in September 2015 and finished in December 2016. It increased the airports capacity to 22 million passengers per year. On 8 December 2016 Terminal 2 was opened for domestic operations and in January 2017 international operations were transferred from Terminal 3.
Gaia BH3 (Gaia DR3 4318465066420528000) is a binary system consisting of a metal-poor giant star with spectral type G and a stellar-mass black hole.Gaia BH3 is located 1926 light years away (590.6 ± 5.8 pc away) in the constellation of Aquila.
Gaia BH2 (Gaia DR3 5870569352746779008) is a binary system consisting of a red giant and what is very likely a stellar-mass black hole.Gaia BH2 is located about 3,800 light years away (1.16 kpc away) in the constellation of Centaurus, making it as of 2024 the third-closest known black hole system to Earth.
The BH-1 was subsequently rebuilt with a Gnome Omega rotary engine and was finally able to fly with two people aboard. It was known as the BH-1 bis in this configuration, and in 1921 won the Czechoslovak national cross-country rally with an average speed of 125 km/h (78 mph) over the 860 km (536 mi) course. The aircraft was damaged in a crash ...
The spectrum of boron monohydride includes a molecular band for the lowest electronic transition X 1 Σ + → A 1 Π with a band head at 433.1 nm (for 0→0) and 437.1 (for 0→1) [3] The spectrum contains P, Q, and R branches. [10] Although BH is a closed shell molecule, it is paramagnetic independent of temperature. [11]
UF 4 + 2 Al(BH 4) 3 → U(BH 4) 4 + 2 Al(BH 4)F 2. It may also be prepared by the solid-state reaction of uranium tetrachloride with lithium borohydride: [1] UCl 4 + 4 LiBH 4 → U(BH 4) 4 + 4 LiCl. Although solid U(BH 4) 4 is a polymer, it undergoes cracking, converting to the monomer. The related methylborohydride complex U(BH 3 CH 3) 4 is ...
