We demonstrate that a massive asymptotic giant branch (AGB) star is a good candidate as the main source of short-lived radionuclides in the early solar system...

PublicationThe Role of Mergers in Galaxy Evolution
In the last decade the importance of mergers in the evolution of galaxies has become evident. In this paper we illustrate this importance by showing examples of...

PublicationThe role of stellar radial motions in shaping galaxy surface brightness profiles
Aims: The physics driving features such as breaks observed in galaxy surface brightness (SB) profiles remains contentious. Here, we assess the importance of...

PublicationThe Role of the Accretion Disk, Dust, and Jets in the IR Emission of Low-luminosity Active Galactic Nuclei
We use recent high-resolution infrared (IR; 1-20 μm) photometry to examine the origin of the IR emission in low-luminosity active galactic nuclei (LLAGN). The...

PublicationThe role of the chromospheric magnetic canopy in the formation of a sunspot penumbra
Context. While it is conjectured that a chromospheric canopy plays a role in penumbra formation, it has been difficult to find observational evidence of the...

PublicationThe RoPES project with HARPS and HARPS-N. I. A system of super-Earths orbiting the moderately active K-dwarf HD 176986
We report the discovery of a system of two super-Earths orbiting the moderately active K-dwarf HD 176986. This work is part of the RoPES RV program of G- and K...

PublicationThe ROSAT International X-ray/Optical Survey (RIXOS): source catalogue
We describe the ROSAT International X-ray/Optical Survey (RIXOS), a medium-sensitivity survey and optical identification of X-ray sources discovered in ROSAT...

PublicationThe ROSAT UK Medium Sensitivity Survey: optical identification and relation to X-ray spectral properties
We present the first results on the optical identification of 89 sources with S(0.5-2 keV)>=1.7x10^-14 erg s^-1 cm^-2 detected in eight ROSAT Position Sensitive...

PublicationThe Rossiter-McLaughlin effect revolutions: an ultra-short period planet and a warm mini-Neptune on perpendicular orbits
Comparisons of the alignment of exoplanets with a common host star and each other can be used to distinguish among concurrent evolution scenarios for the star...
