Context: Advancements in the field of exoplanetary research have extended radial velocity (RV) observations from optical to near-infrared (nIR) domain. M dwarf stars, characterized by their lower masses and higher prevalence rocky planets, become a focal point investigation. This study uses data spectropolarimeter SPIRou available literature HARPS CARMENES spectrographs operating analyze RVs two nearby dwarfs, Gl 480 382. Aims: work aims detect characterize companions around 382 mitigating...

Transiting planets with orbital periods longer than 40 d are extremely rare among the 5000+ discovered so far. The lack of discoveries this population poses a challenge to research into planetary demographics, formation, and evolution. Here, we present detection characterization HD 88986 b, potentially transiting sub-Neptune, possessing longest period known small (<4 R ⊕ ) precise mass measurement ( σ M /M > 25%). Additionally, identified presence massive companion in wider orbit...
Models that postulate the existence of hidden sectors address contemporary questions, such as source baryogenesis and nature dark matter. Neutron-to-hidden-neutron oscillations are among possible mixing processes have been tested with ultracold neutron storage passing-through-wall experiments to set constraints on oscillation period τ_{nn^{'}}. These searches probe a function mass splitting due neutron-hidden-neutron energy degeneracy. In this work, we present new limit derived from...
Abstract The detection of stellar variability often relies on the measurement selected activity indicators, such as coronal emission lines and nonthermal emissions. On flip side, effective temperature is normally seen one key fundamental parameters (with mass radius) to understanding basic physical nature a star its relation with environment (e.g., planetary instellation). We present novel approach for measuring disk-averaged variations sub-Kelvin accuracy inspired by algorithms developed...
We report the discovery of a super-Earth candidate orbiting nearby mid M dwarf Gl\,725A using radial velocity (RV) method. The planetary signal has been independently identified high-precision RVs from SOPHIE and SPIRou spectrographs, in optical near-infrared domains, respectively. modelled stellar activity jointly with planet two Gaussian Processes, one for each instrument to account chromaticity instrumental systematics, along Keplerian model. is significantly detected RV semi-amplitude...

Oscillations of the neutron into a hidden sector particle are processes predicted in various Standard Model extensions. This extra channel for disappearance has not been tested experimentally large portions oscillation parameter space. Several efforts have recently made on revising time limits at low mass-splitting ultra-cold (UCN) storage experiments, and larger passing-through-wall experiments. In this work, we present expected sensitivity an experiment searching oscillations intermediate...
