The Advanced Spectral Library (ASTRAL): Reference Spectra for Evolved M-Stars

Kenneth G. Carpenter, Krister E. Nielsen, Gladys V. Kober +3

The HST Treasury Program "Advanced Spectral Library Project: Cool Stars" was designed to collect representative, high quality ultraviolet spectra of eight evolved F-M type cool sta…

GHRS Observations of Cool, Low-Gravity Stars. VI Mass-Loss Rates and Wind Parameters for M Giants

Gioia Rau, Krister E. Nielsen, Kenneth G. Carpenter +1

The photon-scattering winds of M-giants absorb parts of the chromospheric emission lines and produce self-reversed spectral features in high resolution {\it HST}/GHRS spectra. Thes…

ALMA observations of the "fresh" carbon-rich AGB star TX Piscium. The discovery of an elliptical detached shell

Magdalena Brunner, Marko Mecina, Matthias Maercker +4

Aims. The carbon-rich asymptotic giant branch (AGB) star TX Piscium (TX Psc) has been observed multiple times during multiple epochs and at different wavelengths and resolutions, s…

VLTI-GRAVITY measurements of cool evolved stars: I. Variable photosphere and extended atmosphere of the Mira star R Peg

M. Wittkowski, G. Rau, A. Chiavassa +7

Dynamic model atmospheres of Mira stars predict variabilities in the photospheric radius and in atmospheric molecular layers which are not yet strongly constrained by observations.…

Exoplanet Diversity in the Era of Space-based Direct Imaging Missions

Ravi Kopparapu, Eric Hebrard, Rus Belikov +55

This whitepaper discusses the diversity of exoplanets that could be detected by future observations, so that comparative exoplanetology can be performed in the upcoming era of larg…
