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 ...

Asteroseismology of Exoplanet Host Stars
, 2015 Asteroseismology is among the most powerful observational tools to determine fundamental properties of stars. Space-based photometry has recently enabled the systematic detection of oscillations in exoplanet host stars, allowing a combination of ...

TOI-4600 b and c: Two Long-period Giant Planets Orbiting an Early K Dwarf
The Astrophysical Journal Letters, 2023 We report the discovery and validation of two long-period giant exoplanets orbiting the early K dwarf TOI-4600 ( V = 12.6, T = 11.9), first detected using observations from the Transiting Exoplanet Survey Satellite (TESS) by the TESS Single Transit ...

Hyades Member K2-136c: The Smallest Planet in an Open Cluster with a Precisely Measured Mass
The Astronomical Journal, 2023 K2-136 is a late-K dwarf (0.742 ± 0.039 M _⊙ ) in the Hyades open cluster with three known, transiting planets and an age of 650 ± 70 Myr. Analyzing K2 photometry, we found that planets K2-136b, c, and d have periods of 8.0, 17.3, and 25.6 days and radii

Radial Velocities as an Exoplanet Discovery Method
, 2017 The precise radial velocity technique is a cornerstone of exoplanetary astronomy. Astronomers measure Doppler shifts in the star's spectral features, which track the line-of/sight gravitational accelerations of a star caused by the planets orbiting it ...

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

The Prospect of Detecting Volcanic Signatures on an ExoEarth Using Direct Imaging
The Astronomical Journal, 2023 The James Webb Space Telescope (JWST) has provided the first opportunity of studying the atmospheres of terrestrial exoplanets and estimating their surface conditions.

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 ...
