Variability of Known Exoplanet Host Stars Observed by TESS

The Astronomical Journal, 2023
Both direct and indirect methods of exoplanet detection rely upon detailed knowledge of the potential host stars. Such stellar characterization allows for accurate extraction of planetary properties, as well as contributing to our overall understanding ...

Detection of Exoplanets based on the Transit Method

Highlights in Science, Engineering and Technology, 2023
Exoplanets are planets orbiting a star other than the Sun. These exoplanets may exist in many different forms, such as a hot Jupiter and super earth. Detecting is the first step to further studying the properties of these exoplanets. In this paper, based on data of star Qatar-1 gathered from July 22nd 2022, a light flux curve is developed during the ...

Optimal method for exoplanet detection by spectral and angular differential imaging [PDF]

SPIE Proceedings, 2010
ABSTRACT In the context of the SPHERE planet “nder project, we further develop and characterize a recently proposedmethod for the ecient direct detection of exoplanets f rom the ground using spectral and angular dierentialimaging. The method, called ANDROMEDA, combines images appropriately into pseudo-dataŽ, then uses allof them in a Maximum ...

A new method for finding nearby white dwarfs exoplanets and detecting biosignatures

Monthly Notices of the Royal Astronomical Society, 2022
ABSTRACT We demonstrate that the James Webb Space Telescope (JWST) can detect infrared (IR) excess from the blended light spectral energy distribution of spatially unresolved terrestrial exoplanets orbiting nearby white dwarfs. We find that JWST is capable of detecting warm (habitable-zone; Teq = 287 K) Earths or super-Earths and hot ...

The 0.5MJ transiting exoplanet WASP-13b [PDF]

, 2009
We report the discovery of WASP-13b, a low-mass $ M_{\rm p} = 0.46 ^_~M_J$ transiting exoplanet with an orbital period of 4.35298 $\pm$ 0.00004 days. The transit has a depth of 9 mmag, and although our follow-up photometry does not allow us to constrain ...

Assessing telluric correction methods for Na detections with high-resolution exoplanet transmission spectroscopy [PDF]

Monthly Notices of the Royal Astronomical Society, 2021
ABSTRACT Using high-resolution ground-based transmission spectroscopy to probe exoplanetary atmospheres is difficult due to the inherent telluric contamination from absorption in Earth’s atmosphere. A variety of methods have previously been used to remove telluric features in the optical regime and calculate the planetary transmission ...
