In 2018, Solar Cycle 24 entered into a solar minimum phase. During this period, 11 million zenithal night sky brightness (NSB) data were collected at different...
Nature of a shell of young stars in the outskirts of the Small Magellanic Cloud
Context. Understanding the evolutionary history of the Magellanic Clouds requires an in-depth exploration and characterization of the stellar content in their...
Nature versus nurture: distinguishing effects from stellar processing and chemical evolution on carbon and nitrogen in red giant stars
The surface [C/N] ratios of evolved giants are strongly affected by the first dredge-up (FDU) of nuclear-processed material from stellar cores. C and N also...
Near infrared light variations of chemically peculiar stars. The SrCrEu stars
Twenty magnetic Chemically Peculiar (CP2) stars of the SrCrEu subgroup mostly brighter than the 7.5 visual magnitude have been investigated in the near infrared...
Near infrared light variations of CP stars. The SiSrCrEu stars
Twelve magnetic Chemically Peculiar (CP2) stars of the SiSrCrEu subgroup mostly brighter than the 7.5 visual magnitude have been investigated in the infrared at...
Near infrared monitoring of a sample of blazars with the Carlos Sanchez Telescope.
Results of a program of near-IR monitoring of a sample of blazars and miniblazars observed during 1990 and 1991 with the Carlos Sanchez Telescope, in Teide...
Near infrared observations of the H II region S 146
Near infrared observations between 0.7 and 5 microns of the irregular H II region S 146 are reported. A source found near the center of the nebula is identified...
Observations of the Local Arm have been carried out in the near-infrared with the 1.5 m ``Carlos Sanchez'' telescope in Tenerife. A model of the disc with...
Near infrared observations of the truncation of stellar disks
We present a first study of truncation of the stellar disks of spiral galaxies in the near infrared. Observations of NGC 4013, NGC 4217, NGC 6504 and NGC 5981...
