How the moving planets were watched, named and found, and what a transit is.
Why Stellar Black Hole matters
Stellar Black Hole reveals strong gravity through companion motion, accretion radiation, lensing, or gravitational waves.
How to read Stellar Black Hole
Infer mass with multiple observations rather than treating every dark companion as proven.
Stellar Black Hole in practice: an example
Gas spiraling toward a black hole can emit X-rays before crossing the event horizon.
Where readings of Stellar Black Hole go wrong
A black hole is not a cosmic vacuum cleaner; distant gravity follows its mass.
