El cúmulo del Coronet es una región joven, compacta y el laboratorio natural más cercano para estudiar los procesos de formación estelar y la evolución temprana de estrellas y discos en cúmulos de baja masa. Utilizamos imágenes de alta resolución de la cámara PANIC\Magellan, y datos de las misiones Gaia DR3, APEX y Herschel, analizando en detalle las estructuras a pequeña escala, la...
Lyman-alpha observations are widely used to study hydrogen exospheres. At high altitudes, measured intensity can often be approximated as proportional to hydrogen density integrated along the line of sight. At lower altitudes, the exosphere becomes optically thick, and absorption and multiple scattering produce a nonlocal relation between density and observed intensity. Full radiative-transfer...
The cosmological constant Λ, the leading candidate driving cosmic acceleration, remains poorly constrained at sub-galactic scales. Current bounds come from solar-system tests via planetary perihelion precession (10⁻³⁹–10⁻⁴³ m⁻²) or from stellar orbits near Sgr A* (∼5.67×10⁻⁴⁰ m⁻², the tightest sub-galactic bound to date), but the solar-neighborhood scale has not been systematically exploited...
