Determining something's radial velocity—how fast it is moving towards or away from you—is quite easy. By taking note of something called the Doppler effect and making close observations of the ...

This temperature stability is comparable to the best stability demonstrated for Doppler spectrometers currently achieving m s−1 radial velocity precision. We discuss the challenges of using ...

When [Michael Rechtin] learned about Radial Vector Reducers, the underlying research math made his head spin, albeit very slowly. Realizing that it’s essentially a cycloidal drive meshed with a ...

Voyant Photonics develops an FMCW LiDAR sensor with highly accurate detection and tracking of moving objects up to 200 meters ...

Do all exoplanets known as “hot” Jupiters orbit alone in their respective solar systems, as has long been observed? This is what a recent study | Space ...
