ARRAKIS: Atlas of Resonance Rings as Known In S4G
Resonance rings and pseudorings (here collectively called "rings") are thought to be related to the gathering of material near dynamical resonances caused by non-axisymmetries... -
A frequency Comb calibrated solar atlas
The solar spectrum is a primary reference for the study of physical processes in stars and their variation during activity cycles. High resolution spectra of the Sun are easily... -
Model 1D (LHD) and 3D (CO5BOLD) spectra
To derive space velocities of stars along the line of sight from wavelength shifts in stellar spectra requires accounting for a number of second-order effects. For most stars,... -
A catalogue of Paschen-line profiles
We have assembled an atlas of line profiles of the Paschen Delta (P-{delta}) line at 10049{AA} for the use of stellar modelling. For a few stars we have substituted the Paschen... -
Atmospheric parameters of stars for UV models
The spectral predictions of stellar population models are not as accurate in the ultra-violet (UV) as in the optical wavelength domain. One of the reasons is the lack of... -
MILES atmospheric parameters
Empirical libraries of stellar spectra are used to classify stars and synthetize stellar populations. MILES is a medium spectral-resolution library in the optical domain... -
540-690nm Solar Atlas
Astronomical research dealing with accurate radial velocity measurements need reliable astronomical standards to calibrate the spectrographs and to assess possible systematics.... -
Atmospheric parameters for 1273 stars
Empirical libraries of stellar spectra play an important role in different fields. For example, they are used as reference for the automatic determination of atmospheric... -
Torun catalog of post-AGB and related objects
With the ongoing AKARI infrared sky survey, of much greater sensitivity than IRAS, a wealth of post-AGB objects may be discovered. It is thus time to organize our present... -
Spectroscopic atlas of HD175640
We present a high resolution spectral atlas of the HgMn star HD 175640 covering the 3040-10000{AA} region. UVES spectra observed with 90000-110000 resolving power and signal to... -
Spectra of southern late-type dwarfs
We present Echelle spectra of 91 late-type dwarfs, of spectral types from F to M and of different levels of chromospheric activity, obtained with the 2.15-m telescope of the... -
Atlas of B6-A2 hyper- and supergiants
We present an atlas of spectra of 5 emission-line stars: the low-luminosity luminous blue variables (LBVs) HD 168625 and HD 160529, the white hypergiants (and LBV candidates) HD... -
Spectrophotometric atlas of symbiotic stars
A multi-epoch, absolute-fluxed spectral atlas extending from about 3200 to 9000{AA} is presented for 130 symbiotic stars, including members of the LMC, SMC and Draco dwarf... -
ELODIE archive
We present a database of 908 stellar spectra of 709 stars in the wavelength range 410 to 680 nm obtained with the ELODIE spectrograph. The archive provides a large coverage of... -
IUE Atlas of B-Type Stellar Spectra
The IUE Atlas of B-type Stellar Spectra is an atlas of B-type spectra consisting of short-wavelength, high-resolution data from the International Ultraviolet Explorer archive,... -
High Resolution Atlas of Symbiotic Stars
This catalog contains a high resolution atlas of both northern and southern sky symbiotic stars. It represents an all-sky optical survey of symbiotic stars using Echelle... -
An Ultraviolet Atlas of Quasar and Blazar Spectra
This atlas contains the ultraviolet spectra of 70 quasars, blazars, and Seyfert 1 galaxies that were produced by combining over 100 low resolution spectra from the International... -
IUE Atlas of O-Type Stellar Spectra
The International Ultraviolet Explorer Atlas of O-Type Spectra From 1200 to 1900 A (Walborn et el. 1985) lists normalized fluxes and flux quality factors, splice points, and... -
Leiden/Argentine/Bonn (LAB) Survey of Galactic HI
The LAB survey contains the final data release of observations of 21-cm emission from Galactic neutral hydrogen over the entire sky, merging the Leiden/Dwingeloo Survey (LDS:... -
Atlas of Galactic Neutral Hydrogen
The Leiden/Dwingeloo HI survey mapped the 21-cm spectral line emission over the entire sky above declinations of -30 degrees using a grid spacing of ~ 0.5 degree and a velocity...
