Surface temperatures Tsurf (𝑋C+O, C/O) for varying Psurf (from left to right: 1, 10, and 100 bar). For comparability, the internal temperatures Tint (185, 104, and 56 K, respectively) were

Atmospheric conditions in the case with Sp = 0.4 S0, pN2 = 1.0 bar, pCO2 = 0.1 bar. Each case shows (a) horizontal distribution of surface temperature, (b) horizontal distribution

Artistic renderings of representative small self-cleaving ribozymes. Structures are shown in their native, substrate-free, trans-acting forms to emphasize intrinsic architectural organization rather than the catalytic conformation adopted during cleavage. Each

Space-based Sunshade – University of Innsbruck An international research team including Stefan Kimeswenger, astrophysicist at the University of Innsbruck, has tested a new approach to studying Earth-like exoplanets. The idea

Best-fit orbit solutions. Here we show the on-sky orbit traced by Eps Ind Ab in panel (a); the evolution of on-sky separation and position angle of the planet during our

The top panel are the inner and outer HZ limits for main-sequence stars as a function of stellar mass, according to (R. K. Kopparapu et al. 2013). The bottom panel
