Neural translation for Stokes inversion and synthesis
Context. The physical conditions in stellar atmospheres, such as temperature, velocity, and magnetic fields, can be obtained by interpreting solar spectro...
Neutral carbon and highly excited CO in a massive star-forming main sequence galaxy at z = 2.2
We used the Plateau De Bure Interferometer to observe multiple CO and neutral carbon transitions in a z = 2.2 main sequence disk galaxy, BX610. Our observation...
Neutral oxygen spectral line formation revisited with new collisional data: large departures from LTE at low metallicity
Aims: A detailed study is presented, including estimates of the impact on elemental abundance analysis, of the non-local thermodynamic equilibrium (non-LTE)...
New and updated stellar parameters for 71 evolved planet hosts. On the metallicity-giant planet connection<xref ref-type="fn" rid="FN1"><xref ref-type="fn" rid="FN2">⋆<xref ref-type="fn" rid="FN3">⋆⋆
Context. It is still being debated whether the well-known metallicity-giant planet correlation for dwarf stars is also valid for giant stars. For this reason...
New and updated stellar parameters for 90 transit hosts. The effect of the surface gravity
Context. Precise stellar parameters are crucial in exoplanet research for correctly determining the planetary parameters. For stars hosting a transiting planet...
A 34'x34' field centred on the spiral galaxy M 81 has been searched for emission-line objects using the prime focus wide field camera (WFC) of the 2.54 m Isaac...
New constraints on the central mass contents of Omega Centauri from combined stellar kinematics and pulsar timing
Aims. We performed a combined analysis of stellar kinematics with line-of-sight accelerations of millisecond pulsars (MSPs) to probe the mass content of Omega...
New constraints on the formation and settling of dust in the atmospheres of young M and L dwarfs
Context. Gravity modifies the spectral features of young brown dwarfs (BDs). A proper characterization of these objects is crucial for the identification of the...
New constraints on the membership of the T dwarf S Ori 70 in the σ Orionis cluster
Aims:The nature of S Ori 70 (S Ori J053810.1-023626), a faint mid-T type object found towards the direction of the young σ Orionis cluster, is still under...
