Abstract This study aims to identify exemplary science cases for observing N 2 O, CH 3 Cl, and Br in exoplanet atmospheres at abundances consistent with biogenic production using a space-based mid-infrared nulling interferometric observatory, such as the Large Interferometer For Exoplanets (LIFE) mission concept. We use set of scenarios derived from chemical kinetics models that simulate atmospheric response varied levels O -rich terrestrial planet produce forward our LIFE sim observation...
The Large Interferometer For Exoplanets (LIFE) is a proposed space mission that enables the spectral characterization of thermal emission exoplanets in solar neighborhood. designed to search for global atmospheric biosignatures on dozens temperate terrestrial and it will naturally investigate diversity other worlds. Here, we review status concept, discuss key parameters, outline trade-offs related mission's architecture. In preparation an upcoming concept study, define baseline based...
Some sub-Neptune planets may host habitable conditions; for example "Hycean" worlds with H2 envelopes over liquid water oceans can maintain potentially hospitable pressures and temperatures at their surface. Recent JWST observations of K2-18b TOI-270d have shown that such could be compelling targets biosignature searches, given extended scale heights therefore large atmospheric signatures. Methylated biosignatures, a broad group gases generated by biological attachment CH3 to an...

At its meeting the Commission adopted cipher code for astronomical telegrams, proposed by President, with two minor alterations, and agreed that new was to be used from 1935 Nov. 1. The corrected is given below in this volume (p. 391). also asked an annual grant of 1200 Swiss francs Bureau Astronomical Telegrams until next Union. (A joint discussion 20 reported latter Commission. p. 309.)
