WebExoplanet host stars. The observational study of extrasolar planetary systems is a very recent topic. Instruments capable of detecting the radial-velocity variations of a solar-like star induced by orbiting Jupiter-like planets were built in the 1970s. These led to the detection of the first extrasolar planet in 1995, a hot Jupiter in a very ... WebThe size of the habitable zone clearly depends on the luminosity of the star, which determines the equilibrium temperature of the planet. However, modern models for the range of the habitable zone take into account more subtle effects, such as the effect of the carbonate-silicate cycle in regulating carbon dioxide in a planet's atmosphere. star of bethlehem to appear

Luminosity is an absolute measure of radiated electromagnetic power (light), the radiant power emitted by a light-emitting object over time. In astronomy, luminosity is the total amount of electromagnetic energy emitted per unit of time by a star, galaxy, or other astronomical objects.
