Discovery of a double white dwarf in the Galactic globular cluster NGC 6397

Fabian Göttgens, Marilyn Latour, Ulrich Heber +4

Binaries in the cores of globular clusters are known to prevent the gravitational collapse of the cluster, and simulations predict that the core of NGC 6397 contains a large number…

Tracing stellar rotation in young massive LMC clusters

Sebastian Kamann, Nate Bastian, Florian Niederhofer +8

We present a detailed analysis of stellar rotation along the main sequences of NGC 1866 and NGC 1856, two young (~200-300 Myr) massive clusters in the Large Magellanic Cloud, using…

Searching for exotic object companions in the dense core of NGC 362: a multi-wavelength and multi-epoch photometric analysis

Greta Ettorre, Emanuele Dalessandro, Cristina Pallanca +8

The dense cores of globular clusters (GCs) are efficient environments for the production of exotic stellar populations, including millisecond pulsars (MSPs), low-mass X-ray binarie…

Studying Binary Systems in Omega Centauri with MUSE: II. Observational constraints on the orbital period distribution

S. Saracino, S. Kamann, F. Wragg +8

Omega Centauri ( Cen) is one of the most complex star clusters in the Milky Way, and likely the stripped nucleus of an accreted dwarf galaxy. Being the subject of debate between…

A stellar census in globular clusters with MUSE. Metallicity spread and dispersion among first-population stars

M. Latour, S. Kamann, S. Martocchia +3

Multiple populations are ubiquitous in the old massive globular clusters (GCs) of the Milky Way. It is still unclear how they arose during the formation of a GC. The topic of iron…

Binary properties of the globular cluster 47 Tuc (NGC 104). A dearth of short-period binaries

Johanna Müller-Horn, Fabian Göttgens, Stefan Dreizler +4

Spectroscopic observations of binary stars in globular clusters are essential to shed light on the poorly constrained period, eccentricity, and mass ratio distributions and to deve…

Studying Binary Systems in Omega Centauri with MUSE. I. Detection of Spectroscopic Binaries

F. Wragg, S. Kamann, S. Saracino +6

NGC 5139 ( Cen), is the closest candidate of a Nuclear Star Cluster that has been stripped of its host galaxy in the Milky Way. Despite extensive studies through the last decade…

A false positive transit candidate for EPIC 211101996 from K2 and TESS data identified as background eclipsing binary Gaia DR3 66767847894609792

René Heller, Milena Hüschen, Jan-Vincent Harre +1

Transiting planets around young stars are hard to find due to the enhanced stellar activity. Only a few transiting planets have been detected around stars younger than 100 Myr. We…

A giant exoplanet orbiting a very low-mass star challenges planet formation models

J. C. Morales, A. J. Mustill, I. Ribas +179

Statistical analyses from exoplanet surveys around low-mass stars indicate that super-Earth and Neptune-mass planets are more frequent than gas giants around such stars, in agreeme…

A candidate super-Earth planet orbiting near the snow line of Barnard's star

I. Ribas, M. Tuomi, A. Reiners +60

At a distance of 1.8 parsecs, Barnard's star (Gl 699) is a red dwarf with the largest apparent motion of any known stellar object. It is the closest single star to the Sun, second…

The MICADO first light imager for the ELT: overview, operation, simulation

Richard Davies, João Alves, Yann Clénet +98

MICADO will enable the ELT to perform diffraction limited near-infrared observations at first light. The instrument's capabilities focus on imaging (including astrometric and high…
