This database is a collection of maps created from the 28 SAS-2 observation files. The original observation files can be accessed within BROWSE by changing to the SAS2RAW...

The IPCIMAGE database contains information from the Imaging Proportional Counter aboard HEAO 2, the Einstein Observatory. Einstein incorporated a high-resolution X-ray telescope...

The HRIIMAGE database table contains information from the High Resolution Imager aboard HEAO 2, the Einstein Observatory. Einstein incorporated a high-resolution X-ray telescope...

The European Space Agency's satellite COS-B was dedicated to gamma-ray astronomy in the energy range 50 MeV to 5 Gev and carried a single spark chamber telescope with...

This database table contains the images from two EXOSAT LE telescopes with the channel multiplier array (CMA) detectors in the focal plane. The CMA/telescope combination covers...

This research paper presents a comprehensive analysis of RR Lep and BF Vel, two southern short-period semi-detached oscillating Algols (oEA stars), which are shown to be triple...

The Neptunian desert and savanna have been recently found to be separated by a ridge, an overdensity of planets in the ~3-5 days period range. These features are thought to be...

Young planetary systems represent an opportunity to investigate the early stages of (exo)planetary formation because the gravitational interactions have not yet significantly...

Measurements of the obliquities in exoplanet systems have revealed some remarkable architectures, some of which are very different from the Solar System. Nearly 200 obliquity...

K2-24 is a planetary system composed of two transiting low-density Neptunians locked in an almost perfect 2:1 resonance and showing large TTVs, i.e., an excellent laboratory to...

We aim to constrain the chemo-dynamical properties of the Sagittarius (Sgr) dwarf galaxy using carbon abundances. At low metallicities in particular, these properties reveal the...

The Baade-Wesselink method, also known as the pulsation parallax method allows us to estimate distances to individual pulsating stars. Accurate geometric parallaxes obtained by...

OJ 287 is a bright blazar with century-long observations, and one of the strongest candidates to host a supermassive black hole binary. Its polarisation behaviour between 2015...

Young exoplanets and their corresponding host stars are fascinating laboratories for constraining the time-scale of planetary evolution and planet-star interactions. However,...

This paper investigates the neutral gas phase of galactic winds via the Na I D{lambda}{lambda}5890, 5895{AA} feature within z ~ 0.04 MaNGA galaxies and directly compares their...

Correlated orientations of quasar optical and radio polarization, and of radio jets, have been reported on Gpc scales, possibly arising from intrinsic alignment of spin axes....

Our objective is to investigate the distribution of dust and associated large-scale structures of the Galaxy using optical linear polarization measurements of various open...

We present a one-dimensional, local thermodynamic equilibrium homogeneous analysis of 132 stars observed at high resolution with ESPaDOnS. This represents the largest sample...

Line splitting in spectral lines is observed in various types of stars due to phenomena such as shocks, spectroscopic binaries, magnetic fields, spots, and non-radial modes. In...
