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...
Near-term detectability of terrestrial extrasolar planets: TEP network observations of CM Draconis
Results from a photometric search for extrasolar planetary transits across the eclipsing binary CM Dra are presented. The TEP (Transits of Extrasolar Planets)...
Near-ultraviolet absorption distribution of primitive asteroids from photometric surveys: II. Collisional families
Context. Primitive asteroids consisting of mainly phyllosilicates and opaque minerals have great variation at near-ultraviolet (NUV) wavelengths (0.35–0.5 μm)...
Near-ultraviolet absorption distribution of primitive asteroids from spectrophotometric surveys. I. Radial distribution
Context. Hydrated minerals, such as phyllosilicates, on asteroids can provide constraints on the temperature or compositional distribution of the early Solar...
Near-ultraviolet to visible spectroscopy of the Themis and Polana-Eulalia complex families
Context. Spectrophotometry data of asteroids obtained in the 1980s showed that there are large variations in their near-ultraviolet (NUV) reflectance spectra...
Nearby supernova host galaxies from the CALIFA Survey. I. Sample, data analysis, and correlation to star-forming regions
We use optical integral field spectroscopy (IFS) of nearby supernova (SN) host galaxies (0.005 2.4 Gyr, respectively) than the massive SN Ia hosts (0.04%, 2.01%...
Nebular emission and the Lyman continuum photon escape fraction in CALIFA early-type galaxies
We use deep integral field spectroscopy data from the CALIFA survey to study the warm interstellar medium (wim) over the entire extent and optical spectral...
Neutral carbon and highly excited CO in a massive star-forming main sequence galaxy at z = 2.2
We used the Plateau De Bure Interferometer to observe multiple CO and neutral carbon transitions in a z = 2.2 main sequence disk galaxy, BX610. Our observation...
