Kepler 1627A is a G8V star previously known to host a 3.8 R _⊕ planet on a 7.2 day orbit. The star was observed by the Kepler space telescope because it is nearby ( d = 329 pc) and it resembles the Sun. Here, we show using Gaia kinematics, TESS ste

Double electron capture is a rare nuclear decay process in which two orbital electrons are captured simultaneously in the same nucleus. Measurement of its two-neutrino mode would provide a new reference for the calculation of nuclear matrix elements
