The UVMag space project: UV and visible spectropolarimetry of massive stars

摘要: UVMag is a medium-size space telescope equipped with high-resolution spectropolarimetrer working in the UV and visible domains. It will be proposed to ESA for future M mission. allow scientists study all types of stars as well e.g. exoplanets interstellar medium. particularly useful massive stars, since their spectral energy distribution peaks UV. us circumstellar environment (in particular stellar wind) spectroscopically great details. Moreover, UVMag's polarimetric capabilities we able, first time, measure magnetic field simultaneously at surface wind lines, i.e. completely map magnetosphere.
