Spectroscopic Transit Search: a self-calibrating method for detecting planets around bright stars [PDF]

, 2019
We search for transiting exoplanets around the star $\beta$ Pictoris using high resolution spectroscopy and Doppler imaging that removes the need for standard star observations.

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 ...

Searching for Exoplanets Using a Microresonator Astrocomb [PDF]

, 2018
Detection of weak radial velocity shifts of host stars induced by orbiting planets is an important technique for discovering and characterizing planets beyond our solar system.

The Comparison of Five Methods of Detecting Exoplanets

Highlights in Science, Engineering and Technology, 2023
Detecting exoplanets has become a hot topic, where various detection scenarios have been proposed. Five of these methods have all found more than 50 exoplanets, which are the transit method, the radial velocity method, the microlensing method, the imaging method, and the timing method.

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 ...

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 ...

Detecting the Signatures of Uranus and Neptune [PDF]

, 2011
With more than 15 years since the the first radial velocity discovery of a planet orbiting a Sun-like star, the time baseline for radial velocity surveys is now extending out beyond the orbit of Jupiter analogs.

Speckle noise reduction techniques for high-dynamic range imaging [PDF]

, 2007
High-dynamic range imaging from space in the visible, aiming in particular at the detection of terrestrial exoplanets, necessitates not only the use of a coronagraph, but also of adaptive optics to correct optical defects in real time.

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 ...

The Rossiter-McLaughlin effect in Exoplanet Research

, 2017
The Rossiter-McLaughlin effect occurs during a planet's transit. It provides the main means of measuring the sky-projected spin-orbit angle between a planet's orbital plane, and its host star's equatorial plane.
