The exoplanet 51 Pegasi b [1]lies some 50 light-years from Earth in the constellation of Pegasus. It was discovered in 1995 and will forever be remembered as the first confirmed exoplanet to be found orbiting an ordinary star like the Sun. ...
Two-year polarimetric monitoring of the exoplanet system 51 Peg has been carried out, indicating that there is no orbital phase-dependent periodic variability in linear polarization with amplitudes greater than 0.04% in the and bands. The mean value of one of the Stokes parameters is statistically...
Seeing the light: An artist's impression of 51 Pegasi b The first-ever direct detection of the spectrum of visible light reflected from an exoplanet has been made by an international team of astronomers. Using the High Accuracy Radial velocity Planet Searcher (HARPS) instrument at the ...

51 Pegasi is estimated to be between 7 and 8 billion years old, or several billion years older than our own Sun. While 51 Pegasi b, the exoplanet, is considered a hot Jupiter and not conducive to life, the idea that an alien civilization could exist and be several billion years ahead ...
photons emitted by these planets, facilitating their spectroscopic or photometric characterization. This has led to the discovery of Jupiter analogs such as 51 Eri b5and AF Lep b6, which are inaccessible to transit spectroscopy because their orbits are not passing in front of the host star from ...
transit light curves are the quadratic, square-root and nonlinear four-parameter laws51: Quadratic: $$\frac{I(\mu )}{I(1)}=1-{u}_{1}\left(1-\mu \right)-{u}_{2}{\left(1-\mu \right)}^{2}$$ Square-root: $$\frac{I(\mu )}{I(1)}=1-{s}_{1}\left(1-\mu \right)...
The exoplanet host 51 Pegasi has a widely separated red dwarf companion. Two other, far more distant, stars are also co-moving with this star, showing that they are at least of common Galactic orbit due to a common origin.doi:10.48550/arXiv.1003.3032J. Greaves...
Although exoplanet science is on firm ground now, its future was uncertain when Charbonneau and Seager started out. The first exoplanet, 51 Pegasi b, had just been announced, and almost no-one believed it. The method used to detect it was indirect, the signal was small, and the data wer...
