What is an example of an A type star?

They measure between 1.4 and 2.1 solar masses ( M ☉) and have surface temperatures between 7,600 and 10,000 K. Bright and nearby examples are Altair (A7 V), Sirius A (A1 V), and Vega (A0 V). A-type stars do not have convective zones and thus are not expected to harbor magnetic dynamos.

How many G class stars are in the Milky Way?

“Our Milky Way has as many as 400 billion stars, with seven per cent of them being G-type,” said co-author Matthews. “That means less than six billion stars may have Earth-like planets in our Galaxy.” The vast majority of the exoplanets we’ve discovered have been found using the transit timing method.
