TL;DR: Twinkle as discussed by the authors is the first in a series of cost competitive small satellites managed and financed by Blue Skies Space Ltd. The satellite is based on a high-heritage Airbus platform that will carry a 0.45 m telescope and a spectrometer which will provide simultaneous wavelength coverage from 0.5 to 4.5 μm.

TL;DR: In this paper, the structure of the bromobenzene and the homodimer inside helium droplets was deduced using a combination of laser-induced alignment, Coulomb explosion imaging, and three-dimensional ion imaging.
Proceedings ArticleDOI
Ayty: a New Line-List for Hot Formaldehyde
TL;DR: AYTY as discussed by the authors is a line list for formaldehyde applicable to temperatures up to 1500 K. The line list was computed using the variational ro-vibrational solver TROVE with a refined ab-initio potential energy surface and dipole moment surface.

TL;DR: In this article, simulated transmission spectra for two small, temperate planets (GJ 1214 b and K2-18 b) are presented, giving evidence for significant differences in simulated transit depth when the water vapor continuum is accounted for when compared to models omitting it.
