The Work of Art in the Age of Digital Commodification Open
Digitization is taking over every sphere of life—including the arts. Through the process of digital commodity fetishism, major technology companies threaten to efface the very qualities that make creative expression—particularly the perfor…

High precision ground-based CCD photometry from the Next Generation Transit Survey Open
The Next Generation Transit Survey (NGTS) has now been operating for six years, discovering and characterizing transiting exoplanets around bright stars. We outline the NGTS project, including the Andor CCD cameras used to perform high-pre…

The EBLM project X. Benchmark masses, radii and temperatures for two fully convective M-dwarfs using K2 Open
M-dwarfs are the most abundant stars in the galaxy and popular targets for exoplanet searches. However, their intrinsic faintness and complex spectra inhibit precise characterisation. We only know of dozens of M-dwarfs with fundamental par…

Revised Temperatures For Two Benchmark M-dwarfs -- Outliers No More Open
Well-characterised M-dwarfs are rare, particularly with respect to effective temperature. In this letter we re-analyse two benchmark M-dwarfs in eclipsing binaries from Kepler/K2: KIC 1571511AB and HD 24465AB. Both have temperatures report…

Populating the brown dwarf and stellar boundary: Five stars with transiting companions near the hydrogen-burning mass limit Open
We report the discovery of five transiting companions near the hydrogen-burning mass limit in close orbits around main sequence stars originally identified by the Transiting Exoplanet Survey Satellite (TESS) as TESS Objects of Interest (TO…
