PublicaciónThe first super-Earth detection from the high cadence and high radial velocity precision Dharma Planet Survey
The Dharma Planet Survey (DPS) aims to monitor about 150 nearby very bright FGKM dwarfs (within 50 pc) during 2016-2020 for low-mass planet detection and...

PublicaciónThe flipped orbit of KELT-19Ab inferred from the symmetric TESS transit light curves
Dozens of planets are now discovered with large orbital obliquity, and have become the proof for the dynamical evolution of planetary orbits. In the current...

PublicaciónThe Formation and Disintegration of Magnetic Bright Points Observed by Sunrise/IMaX
The evolution of the physical parameters of magnetic bright points (MBPs) located in the quiet Sun (mainly in the interwork) during their lifetime is studied...

PublicaciónThe Fornax 3D project: PNe populations and stellar metallicity in edge-on galaxies
Context. Extragalactic planetary nebulae (PNe) are useful distance indicators and are often used to trace the dark-matter content in external galaxies. At the...

PublicaciónThe Fornax3D project: Planetary nebulae catalogue and independent distance measurements to Fornax cluster galaxies
Extragalactic planetary nebulae (PNe) offer a way to determine the distance to their host galaxies thanks to the nearly universal shape of the planetary nebulae...

PublicaciónThe fraction of binary systems in the core of five Galactic open clusters
We used deep wide-field photometric observations to derive the fraction of binary systems in a sample of five high-latitude Galactic open clusters. By analysing...

PublicaciónThe fundamental parameters of the Algol binary AI Draconis revisited
We present the results of an analysis of our infrared light curves of the Algol-type binary AI Draconis in the J, H and K bands, and of published light curves...

PublicaciónThe Gaia EDR3 view of Johnson-Kron-Cousins standard stars: the curated Landolt and Stetson collections
Context. In the era of large surveys and space missions, it is necessary to rely on large samples of well-characterized stars for inter-calibrating and...
