Science Quiz | Rare Star V886 Centauri

question:

1. Scientists believe that the star V886 Centauri is composed primarily of carbon and oxygen, with a hydrogen atmosphere and a dense crystalline core. And given the estimated size of its core, on February 13, 2004, the Harvard-Smithsonian Center for Astrophysics (CfA) declared it the largest _______ in the universe. Fill in the blanks.

2. CfA researchers nicknamed the V886 Centauri core after a Beatles song. What’s your nickname? This song is included in the album “Sgt.” Pepper’s Lonely Hearts Club Band.

3. V886 Centauri is a pulsating X star. There are many subtypes of such stars. For example, V886 Centauri is Y-type. The main component of X is an electronically degenerate substance. Y is distinguished by light and appears to pulsate with a period of 30 to 25 minutes. Name X and Y.

4. The body of a star vibrates in different ways. Name the branch of science that studies these vibrations. Based on such studies, astronomers reported in his 2004 that about 90% of V886 Centauri’s mass may have crystallized. This means that the crystalline component weighs at least 5.1 trillion kg.

5. V886 Centauri may be the largest _________ in the universe (see Q1), but what is the name of its largest counterpart on Earth (so far)?In South Africa on January 26, 1905 discovered.
