Astronomical data gathered over time has gaps. Even the most reliable space telescopes suffer from occasional pauses in their otherwise constant watchfulness. Why are gaps a problem? Can’t astronomers just analyze the short chunks of data that don’t have gaps? The answer: Fourier transforms.
Kepler-93b is a super-Earth with a radius of 1.481 Earth radii, plus or minus Long Island.
Gravitational waves passing through our solar system make the Sun ring like a bell. Can their effect be measured to learn about the violent phenomena that caused them?
How do pulsating stars give away their secret identities as binary dance partners? In this paper, the authors demonstrate a new way to not only detect binaries we may have missed in the Kepler data, but also to measure their velocities without spectra.
We have repeatedly seen how Kepler goes above and beyond its original mission of finding exoplanets. Today’s paper is no exception.
The authors present the discovery of a new hot carbon-atmosphere white dwarf with a strong magnetic field. This discovery might help illuminate the origins of a recently found class of white dwarfs.
In the sun, subsurface flows are 20-100 times slower than what is predicted in widely used theoretical models.
Title: SDSS J184037.78+642312.3: The First Pulsating Extremely Low Mass White Dwarf Authors: J. J. Hermes, M. H. Montgomery, D. E. Winget, Warren R. Brown, Mukremin Kilic, Scott J. Kenyon First Author’s Institution: UT Austin, TX 97% of all stars — those with initial masses less than about 8 solar masses — end their lives as […]
Just as seismologists determine the structure of the Earth through surface vibrations, so asteroseismologists do the same for stars
