The 3D morphology of open clusters in the solar neighborhood III: Fractal dimension
Chang Qin, Xiaoying Pang, Mario Pasquato +2
We analyze the fractal dimension of open clusters using 3D spatial data from Gaia DR3 for 93 open clusters from Pang et al. (2024) and 127 open clusters from Hunt & Reffert (2024)…
A possible misaligned orbit for the young planet AU Mic c
H. Yu, Z. Garai, M. Cretignier +98
The AU Microscopii planetary system is only 24 Myr old, and its geometry may provide clues about the early dynamical history of planetary systems. Here, we present the first measur…
Euclid: Field-level inference of primordial non-Gaussianity and cosmic initial conditions
A. Andrews, J. Jasche, G. Lavaux +147
A primary target of the \Euclid space mission is to constrain early-universe physics by searching for deviations from a primordial Gaussian random field. A significant detection of…
The symbiotic star V694 Mon has transitioned from the accreting-only state to the steady burning phase
Ulisse Munari
We propose that the drastic photometric and spectroscopic changes affecting the symbiotic star V694 Mon since 2018, are due to its transition from the accreting-only state to stead…
Identification of ram pressure stripping features in galaxies using citizen science
Jacob P. Crossett, Yara L. Jaffé, Sean L. McGee +6
Ram pressure stripped galaxies are rare cases of environmental evolution in action. However, our ability to understand these galaxies is limited by the small number of identified g…
CHEOPS observations confirm nodal precession in the WASP-33 system
A. M. S. Smith, Sz. Csizmadia, V. Van Grootel +86
Aims: We aim to observe the transits and occultations of WASP-33b, which orbits a rapidly-rotating Scuti pulsator, with the goal of measuring the orbital obliquity via the grav…
