A Sounding Rocket Experiment for Spectropolarimetric Observations with the Lyα Line at 121.6 nm (CLASP)
A team consisting of Japan, USA, Spain, and Norway is developing a high-throughput Chromospheric Lyman-Alpha SpectroPolarimeter (CLASP), which is proposed to...
A special mentoring program for Master's students in astrophysics promoting DEI
In the pursuit of promoting diversity, equity, and inclusion (DEI) in the field of Astrophysics and High Energy Physics, a group of young researchers at the...
A spectral atlas of Landolt stars for a reliable mid-IR spectrophotometric calibration for large telescopes
It is often stated that there is no point in obtaining mid-infrared data with S/N>20, even in the best of cases, because it is impossible to obtain a...
A Spectral Diagnostic for Density-Bounded HII Regions
Our spectral diagnostic based on the intensity of the [OI]λ6300Å line indicates that many observed HII regions are indeed density-bounded. The estimated...
A spectrophotometric study of the peculiar young open cluster Berkeley 87
A spectrophotometric study of the peculiar open cluster Berkeley 87 is presented; the measurements show that most of the members are young, heavily reddened OB...
A spectroscopic analysis of the Trapezium Cluster stars
We consider the Orion Nebula (M 42) within a project aimed at studying the interaction between massive stars and their surrounding ISM. This is an HII region...
A spectroscopic atlas of post-AGB stars and planetary nebulae selected from the IRAS point source catalogue.
The spectroscopic observations were conducted during several runs spanning 15 years from March 1988 to June 2003. The observations from the Southern Hemisphere...
A Spectroscopic Census Of L Dwarfs Observed By Gaia
The ESA cornerstone mission Gaia will revolutionise astronomy observing objects as diverse as minor planets, stars,and galaxies out to QSOs. We estimate that...
