Context. M dwarfs are known to generate the strongest magnetic fields among main-sequence stars with convective envelopes, but we are still lacking a consistent picture of the link between the magnetic fields and underlying dynamo mechanisms, ro[...]texto impreso
Barrio Uña, Juan Abel ; Contreras González, José Luis ; Domínguez Díaz, Alberto ; Carreto Fidalgo, David Friedrich ; Fonseca González, Victoria ; Nievas Rosillo, Mireia ; otros, ... | EDP SCIENCES S A | 2018-11-09Context. The BL Lac object S5 0716+714, a highly variable blazar, underwent an impressive outburst in January 2015 (Phase A), followed by minor activity in February (Phase B). The MAGIC observations were triggered by the optical flux observed in[...]texto impreso
Aims. We explore the capabilities of CARMENES for characterizing hot-Jupiter atmospheres by targeting multiple water bands, in particular, those at 1.15 and 1.4 µm. Hubble Space Telescope observations suggest that this wavelength region is relev[...]texto impreso
Population spike signaling is widely observed both in intact brain and neuronal cultures. Experimental evidence suggests that a locally applied electrical stimulus can shape the network architecture and thus the neuronal response. However, there[...]texto impreso
Caballero, J. A. ; Cortés Contreras, Miriam ; Montes Gutiérrez, David | EDP SCIENCES S A | 2019-08-06We report the detection of a transiting Earth-size planet around GJ 357, a nearby M2.5 V star, using data from the Transiting Exoplanet Survey Satellite (TESS).
