Abstract
We outline some of the highlights of the scientific case for the advancement of stellar high energy physics using the Line Emission Mapper X-ray Probe ( LEM). The key to advancements with LEM lie in its large effective area -- up to 100 times that of the Chandra MEG -- and 1 eV spectral resolution. The large effective area opens up for the first time the ability to study time-dependent phenomena on their natural timescales at high resolution, such as flares and coronal mass ejections, and also opens the sky to much fainter targets than available to Chandra or XMM-Newton.
