The facts on the card
The card carries these facts from its Wikipedia article.
- It is a general model of accretion with multiple applications, such as accretion of the interstellar medium by neutron stars and black holes, or wind mass transfer in binary star systems.
- It is named after Hermann Bondi, Fred Hoyle, and Raymond Lyttleton.
- An initial estimate of the accretion rate for a supersonic wind was derived by Hoyle and Lyttleton in 1939 to explain variations in the climate of the Earth.
Why it is Common
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Bondi–Hoyle–Lyttleton accretion article was read about 3,700 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 61 and blocks with 43: each hit it takes is cut by 17 %.
