U.S. Naval Research Laboratory (NRL) detailed an inverse relationship between the brightness of the solar corona and the ...

The newfound exoplanet, called Kepler-139f, is a gigantic world roughly twice the mass of Neptune and 35 times the mass of ...

When astronomers first discovered exoplanets, they found massive ones orbiting large stars. The technology to detect smaller planets around low-mass, dim red dwarfs took time to develop. By the ...

For radial velocity, we look for red- or blue-shifts in the light received from the star, caused by a planet tugging the star in different directions as it orbits.

The radial velocity technique is needed for this. Together, these methods work in harmony: the transit method spots numerous candidates, which are then verified using global spectrographs, providing ...

Astronomers have made an exciting breakthrough by discovering four sub-Earth exoplanets orbiting Barnard’s Star, our closest single-star neighbor. Using the high-precision MAROON-X instrument on the ...

These instruments measure what's termed 'radial velocity' — the amount by which a star wobbles around the center of mass that it shares with its planets.

Conclusions: The proposed method allows to measure the radial pulse wave within shorter distances compatible with integration in wearables. Leveraging TDK ultrasound MEMS platform, this paves the ...
