Context. According to theory, high-energy emission from the coronae of cool stars can severely erode the atmospheres of orbiting planets. No observational tests...
A scenario of planet erosion by coronal radiation (Corrigendum)
In the notes to Table 1, a unit conversion was incorrect. The text should read 1 MJ Gyr-1 = 6.02e+13 g s-1. As a consequence in the 3rd paragraph of Sect. 3...
Extensive spectroscopic studies of stars with and without planetary systems have concluded that planet host stars are more metal-rich than those without...
An amino acid essential for life is found in interstellar space
The IAC researcher Susana Iglesias-Groth has discovered the existence of tryptophan, an amino acid essential for the formation of proteins and the develoment of...
An Astrophysical Perspective of Life. The Growth of Complexity
The existence of life is one of the most fundamental problems of astrophysics. The intriguing existence of progressively complex and apparently improbable...
Characterizing the Atmospheres of Transiting Rocky Planets Around Late-type Dwarfs
Visible and near-infrared spectra of transiting hot Jupiter planets have recently been observed, revealing some of the atmospheric constituents of their...
Characterizing the Purple Earth: Modeling the Globally Integrated Spectral Variability of the Archean Earth
Ongoing searches for exoplanetary systems have revealed a wealth of planets with diverse physical properties. Planets even smaller than the Earth have already...
Concepts for future missions to search for technosignatures
New and unique opportunities now exist to look for technosignatures (TS) beyond traditional SETI radio searches, motivated by tremendous advances in exoplanet...
Earth like planets albedo variations versus continental landmass distribution
By making use of real information about the continental and oceanic surface distribution of the Earth, and cloudiness data from the International Satellite...
