Latest Variable star Stories
A deep survey of more than 200,000 stars in our Milky Way galaxy has unveiled the sometimes petulant behavior of tiny red dwarf stars.
By discovering the first double star where a pulsating Cepheid variable and another star pass in front of one another, an international team of astronomers has solved a decades-old mystery.
A team of Chinese astronomers have discovered a giant planet close to the exotic binary star system QS Virginis.
About 550 light-years from Earth, a star like our Sun is writhing in its death throes.
An extensive study made with ESOâ€™s Very Large Telescope deepens a long-standing mystery in the study of stars similar to the Sun.
This week, Astronomy & Astrophysics publishes a somewhat unusual research article because it is co-authored by German high-school students.
Ohio State University researchers have found a way to measure distances to objects three times farther away in outer space than previously possible, by extending a common measurement technique.
Whatever dark energy is, explanations for it have less wiggle room following a Hubble Space Telescope observation that has refined the measurement of the universe's present expansion rate to a precision where the error is smaller than five percent.
New, very precise measurements have shown that the rotation of the Milky Way is simpler than previously thought.
Discovery helps solve riddle of where the carbon white dwarfs come from, and what happens to their hydrogen and helium
Variable Star -- Most stars are of nearly constant luminosity. Our own Sun is a good example which goes through practically no measurable variation in brightness. There are, however, stars which do vary in brightness, called variable stars. They fall into two main groups: Intrinsic variables These are stars which have intrinsic variations in brightness, that is the star itself gets brighter and dimmer. There are many types of intrinsic variables, the main types being: -- Mira...
