Aims: The characterisation of the stellar population in young high-mass star-forming regions allows fundamental cluster properties like distance and age to be...
Near-infrared spectroscopy of 1999 JU3, the target of the Hayabusa 2 mission
Context. Primitive asteroids contain complex organic material and ices relevant to the origin of life on Earth. These types of asteroids are the target of...
Near-infrared spectroscopy of the nucleus of comet 124P/Mrkos
We report near-infrared (0.9-2.3 mu m) spectral observations of the bare nucleus of comet 124P/Mrkos taken on two different nights using the Near Infrared...
Near-infrared study of the stellar population of Sh2-152
Context. The discovery of new massive star clusters and massive stellar populations in previously known clusters in our Galaxy by means of infrared studies has...
Near-infrared variability of a sample of galactic carbon Miras
Aims.In this paper we aim to determine the longest pulsation period of infrared carbon stars. Methods: .Forty-seven infrared carbon stars were selected based on...
Near-IR internetwork spectro-polarimetry at different heliocentric angles
Aims:The analysis of near infrared spectropolarimetric data at the internetwork in different regions on the solar surface could offer constraints that reject...
Near-IR narrow-band imaging with CIRCE at the Gran Telescopio Canarias: Searching for Lyα-emitters at z ∼ 9.3
Context. Identifying very high-redshift galaxies is crucial for understanding the formation and evolution of galaxies. However, many questions still remain, and...
Near-IR spectroscopy of planetary nebulae precursors
We present near-IR spectroscopy of a sample of 30 IRAS sources recently identified as late AGB stars, post-AGB stars or early PNe. The spectra obtained are...
Near-IR variability properties of a selected sample of AGB stars
We present the results of a near-infrared monitoring programme of a selected sample of stars, initially suspected to be Mira variables and OH/IR stars, covering...
