AN UNSUPERVISED PATCH-BASED APPROACH FOR EXOPLANET DETECTION BY DIRECT IMAGING
, 2018 International audienceThe search for exoplanet is a very active topic in astronomy. Exoplanet detection by direct imaging requires both dedicated instruments to mask out the host star and careful image processing methods.

Bayesian Methods for Joint Exoplanet Transit Detection and Systematic Noise Characterization [PDF]
The Astronomical Journal, 2020 Abstract The treatment of systematic noise is a significant aspect of transit exoplanet data processing due to the signal strength of systematic noise relative to a transit signal. Typically, the standard approach to transit detection is to estimate and remove systematic noise independently of and prior to a transit detection test.

Surprise Nondetection of Upsilon Andromedae b with MIRC-X and MYSTIC at the CHARA Array
The Astronomical JournalGround-based long baseline interferometry is a powerful tool for characterizing exoplanets that are too close to their host star to be imaged with single-dish telescopes. The CHARA Array can resolve companions down to 0.5 mas, allowing us in principle to

Computer Graphics Forum, EarlyView.We present design considerations for animated transitions of the appearance of 3D spatial datasets in a hybrid Augmented Reality‐desktop context. Such hybrid interfaces combine both traditional and immersive displays to facilitate the exploration of 2D and 3D data representations in the environment in which they are best displayed.

Identifying Exoplanet Candidates Using WaveCeptionNet
The Astronomical JournalIn this study, we propose a wavelet-transform-based light curve representation method and a CNN model based on Inception-v3 for fast classification of light curves, enabling the quick discovery of potentially interesting targets from massive data ...

Using dimers to measure biosignatures and atmospheric pressure for terrestrial exoplanets [PDF]
, 2014 We present a new method to probe atmospheric pressure on Earth-like planets using (O-O) dimers in the near-infrared. We also show that dimer features could be the most readily detectable biosignatures for Earth-like atmospheres and may even be detectable

Toward Instrument-agnostic Exoplanet Candidate Prioritization
The Astronomical JournalWe have developed a novel machine learning (ML) approach for predicting the likelihood of exoplanet candidate confirmation equally capable of performance on both Transiting Exoplanet Survey Satellite (TESS) and Kepler data.

Compared sensitivities of VLT, JWST and ELT for direct exoplanet detection in nearby stellar moving groups [PDF]
, 2010 In the context of exoplanet detection, a large majority of the 400 detected exoplanets have been found by indirect methods. Today, progress in the field of high contrast and angular resolution imaging has allowed direct images of several exoplanetary ...

The Astronomical Journal, 2023 Wavelets are waveform functions that describe transient and unstable variations, such as noise. In this work, we study the advantages of discrete and continuous wavelet transforms (DWTs and CWTs) of microlensing data to denoise them and extract their ...
