Using accurate radial velocity observations of integral sunlight, the background solar velocity noise has been measured at different frequencies of interest for...
The optical properties of low luminosity radio galaxies with radio jets
A morphological description and CCD photometric information for a sample of 24 low luminosity radio galaxies with radio jets are presented. It is concluded that...
The prevalence of neutral gas in massive post-main-sequence nebulae
Results are reported from a CO (J = 2-1) survey of nine type I nebulae using the 12-m NRAO antenna at KPNO; the data are presented in tables, graphs, and...
The radial velocity of the sun as a star and the solar cycle
Radial velocity measurements of the sun as a star using a resonant scattering spectrometer have been obtained at Izaña (Tenerife) during long observing seasons...
The Rotation Speed of the Companion Star in Aquila X-1
We have obtained medium resolution spectra of the neutron star X-ray transient Aql X-1 during quiescence. We determine the spectral type of the companion star...
The search for radial velocity variations in rapidly oscillating AP stars using the Fabry-Perot Interferometric Stellar Oscillation Spectrometer (FP-ISOS)
Radial velocity measurements were taken of a group of Ap stars using an improved FP-ISOS. Observations were made using the 1.5m TCS on Tenerife in May 1987 and...
Several techniques are achieving nowadays the precision levels required to detect few-Earth-mass planets, but still a fruitful path needs to be explored in...
The System Parameters of the Polars MR SER and ST LMi
We obtain the Na I lambda 8183,8195 absorption line radial velocity curves for the polars ST LMi and MR Ser, from which we find the semi-amplitudes to be Kabs...
The TESS Grand Unified Hot Jupiter Survey. II. Twenty New Giant Planets
NASA's Transiting Exoplanet Survey Satellite (TESS) mission promises to improve our understanding of hot Jupiters by providing an all-sky, magnitude-limited...
