Context. M31N 2015-01a (or M31LRN 2015) is a red nova that erupted in January 2015 - the first event of this kind observed in M 31 since 1988. Very few similar...
The JCMT Nearby Galaxies Legacy Survey. VI. The distribution of gas and star formation in M 81
We present the first complete 12CO J = 3-2 map of M 81, observed as part of the Nearby Galaxies Legacy Survey being carried out at the James Clerk Maxwell...
The JWST view of the barred galaxy population in the SMACS0723 galaxy cluster
Context. The cosmic evolution of the barred galaxy population provides key information about the secular evolution of galaxies and the settling of rotationally...
The K-band spectrum of the cataclysmic variable RXJ 0502.8+1624 (Tau 4)
We present the K-band spectrum of the cataclysmic variable RXJ 0502.8+1624 (Tau 4). The spectrum shows a broad, smooth hump, with no absorption lines from the...
The K-dwarf problem and the time-dependence of gaseous accretion to the Galactic disc
In this article we compare and contrast the predictions of models we have published previously, with the most recent observational data on the G-dwarf/K-dwarf...
The planetary system K2-24 is composed of two transiting low-density Neptunians locked in an almost perfect 2:1 resonance and showing large transit time...
The Kepler characterization of the variability among A- and F-type stars. I. General overview
Context. The Kepler spacecraft is providing time series of photometric data with micromagnitude precision for hundreds of A-F type stars. Aims: We present a...
The kinematics of local thick discs do not support an accretion origin⋆
Thick discs are nearly ubiquitous components of the discs of present-day galaxies. It has been proposed that a fraction of their stars have been accreted. Here...
The kinematics of the quadrupolar nebula M 1-75 and the identification of its central star
Context. The link between how bipolar planetary nebulae are shaped and their central stars is still poorly understood. Aims: This paper investigates the...
