An HST Transmission Spectrum of the Closest M Dwarf Transiting Rocky Planet LTT 1445Ab

An HST Transmission Spectrum of the Closest M Dwarf Transiting Rocky Planet LTT 1445Ab

Which rocky exoplanets have atmospheres? This presumably simple question is the first that must be answered to understand the prevalence of nearby habitable planets. A mere 6.9 pc from Earth, LTT 1445A is the closest transiting M dwarf system, and its largest known planet, at 1.31 R _⊕ and 424 K, is...
