Revised Masses for Low-density Planets Orbiting the Disordered M-dwarf System TOI-1266

The Astronomical Journal
We present an analysis of 126 new radial velocity measurements from the MAROON-X spectrograph to investigate the TOI-1266 system, which hosts two known transiting sub-Neptunes at 10.8 and 18.8 days.

Achieving Quantum Limits of Exoplanet Detection and Localization [PDF]

arXiv
Discovering exoplanets in orbit around distant stars via direct imaging is fundamentally impeded by the high dynamic range between the star and the planet. Coronagraphs strive to increase the signal-to-noise ratio of exoplanet signatures by optically rejecting light from the host star while leaving light from the exoplanet mostly unaltered.

Exoplanet Detection : A Detailed Analysis [PDF]

arXiv
The exoplanet detection is the most exciting and challenging field of astronomy. The discovery of many exoplanets has revolutionized our understanding of the formation and evolution of planetary systems and has showed new ways to search for extra terrestrial life.
