HIP 41378 f is a temperate $9.2\pm0.1 R_{\oplus}$ planet with period of 542.08 days and an extremely low density of $0.09\pm0.02$ g cm$^{-3}$. It transits the bright star HIP 41378 (V=8.93), making it an exciting target for atmospheric characterizati

White-light flares from the youngest stars in Orion ', Monthly Notices of the Royal Astronomical Society . https://doi.org/10.1093/mnras/staa1971

We present the detection of high energy white-light flares from pre-main sequence stars associated with the Orion complex, observed as part of the Next Generation Transit Survey (NGTS). With energies up to $5.2\times10^{35}$ erg these flares are some

The Transit and Light Curve Modeller

Autor: Csizmadia, Szilard

Publikováno v: Monthly Notices of the Royal Astronomical Society. 496:4442-4467

Transit and Light Curve Modeller (TLCM), a computer code with the purpose of analysing photometric time series of transits simultaneously with the out-of-transit light variations and radial velocity curves of transiting/eclipsing binary systems, is p

The Role of N2as a Geo-Biosignature for the Detection and Characterization of Earth-like Habitats

Publikováno v: Astrobiology. 19:927-950

Since the Archean, N2 has been a major atmospheric constituent in Earth's atmosphere. Nitrogen is an essential element in the building blocks of life, therefore the geobiological nitrogen cycle is a fundamental factor in the long term evolution of bo

Detectability of biosignatures on LHS 1140 b

Autor: Fabian Wunderlich, Clara Sousa-Silva, Mareike Godolt, John Lee Grenfell, Markus Scheucher, Heike Rauer, Franz Schreier

Terrestrial extrasolar planets around low-mass stars are prime targets when searching for atmospheric biosignatures with current and near-future telescopes. The habitable-zone Super-Earth LHS 1140 b could hold a hydrogen-dominated atmosphere and is a
