Leveraging Movement Representation from Contrastive Learning for Asteroid Detection
To support asteroid-related studies, current motion detectors are utilized to select moving object candidates based on their visualizations and movements in...
LHS 1815b: The First Thick-disk Planet Detected by TESS
We report the first discovery of a thick-disk planet, LHS 1815b (TOI-704b, TIC 260004324), detected in the Transiting Exoplanet Survey Satellite (TESS) survey...
Li abundances in F stars: planets, rotation, and Galactic evolution
Aims: We aim, on the one hand, to study the possible differences of Li abundances between planet hosts and stars without detected planets at effective...
Li abundances in late-type companions to neutron stars and black hole candidates
Following our recent report of a strong Li lambda 6708 resonance line in the secondary of the black hole candidate V404 Cyg, we present here its detection in...
It is argued that internal gravity waves generated by the convective envelope of a star may be effective in producing a weak mixing in its radiative interior...
Li depletion in solar analogues with exoplanets. Extending the sample
Aims: We want to study the effects of the formation of planets and planetary systems on the atmospheric Li abundance of planet host stars. Methods: In this work...
Library of high and mid-resolution spectra in the CA II H & K, Hα, Hβ NA i D1, D2, and He i D3 line regions of F, G, K and M field stars
In this work we present spectroscopic observations centered in the spectral lines most widely used as optical indicators of chromospheric activity (Hα, Hβ, Ca...
