dc.description.abstract | We present extensive ultraviolet (UV) and optical photometric and optical spectroscopic follow-up of supernova (SN) 2021gno by the Precision Observations of Infant Supernova Explosions (POISE) project, starting less than 2 d after the explosion. Given its intermediate luminosity, fast photometric evolution, and quick transition to the nebular phase with spectra dominated by [Ca II] lines, SN 2021gno belongs to the small family of Calcium-rich transients. Moreover, it shows double-peaked light curves, a phenomenon shared with only four other Calcium-rich events. The projected distance from the centre of the host galaxy is not as large as other objects in this family. The initial optical light-curve peaks coincide with a very quick decline of the UV flux, indicating a fast initial cooling phase. Through hydrodynamical modelling of the bolometric light curve and line velocity evolution, we found that the observations are compatible with the explosion of a highly stripped massive star with an ejecta mass of 0.8 Msun and a 56Ni mass of 0.024 Msun. The initial cooling phase (first light-curve peak) is explained by the presence of an extended circumstellar material comprising ~0.01 Msun with an extension of 1100 Rsun. We discuss if hydrogen features are present in both maximum-light and nebular spectra, and their implications in terms of the proposed progenitor scenarios for Calcium-rich transients. | es_ES |

dc.description.resumen | Presentamos un extenso seguimiento ultravioleta (UV) y fotométrico óptico y espectroscópico óptico de la supernova (SN) 2021gno mediante el proyecto Observaciones de precisión de explosiones de supernovas infantiles (POISE), que comienza menos de 2 días después de la explosión. Dada su luminosidad intermedia, rápida evolución fotométrica y rápida transición a la fase nebular con espectros dominados por líneas [Ca II], SN 2021gno pertenece a la pequeña familia de transitorios ricos en calcio. Además, muestra curvas de luz de doble pico, un fenómeno compartido sólo con otros cuatro eventos ricos en calcio. La distancia proyectada desde el centro de la galaxia anfitriona no es tan grande como la de otros objetos de esta familia. Los picos iniciales de la curva de luz óptica coinciden con una disminución muy rápida del flujo UV, lo que indica una rápida fase de enfriamiento inicial. A través del modelado hidrodinámico de la curva de luz bolométrica y la evolución de la velocidad de la línea, encontramos que las observaciones son compatibles con la explosión de una estrella masiva altamente desnuda con una masa eyectada de 0,8 Msol y una masa de 56Ni de 0,024 Msol. La fase de enfriamiento inicial (primer pico de la curva de luz) se explica por la presencia de un material circunestelar extendido que comprende ~0,01 Msol con una extensión de 1100 Rssol. Discutimos si las características del hidrógeno están presentes tanto en el espectro de luz máxima como en el espectro nebular, y sus implicaciones en términos de los escenarios progenitores propuestos para los transitorios ricos en calcio. | es_ES |
