A research team led by astronomers from the University of Tokyo and the National Astronomical Observatory of Japan (NAOJ) has discovered that inclined orbits may be typical rather than rare for ...

In their interiors, stars are structured in a layered, onion-like fashion. In those with solar-like temperatures, the core is followed by the radiation zone. There, the heat from within is led ...

The occultation of stellar active regions during the planetary transit[1] can lead to inaccurate estimates of the characteristics of these exoplanets, especially the spin-orbit tilt angle. This was ...

The great majority of exoplanets discovered so far are orbiting cool, low-mass stars whose properties are relatively similar to the Sun. However, the stellar magnetism of these stars can be ...

The MPG/ESO 2.2-meter telescope at ESO’s La Silla Observatory in Chile captured this colorful view of the bright star cluster NGC 3532. Some of the stars still shine with a hot bluish color, but many ...
