Simultaneous exoplanet detection and instrument aberration retrieval in multispectral coronagraphic imaging

, 2013
High-contrast imaging for the detection and characterization of exoplanets relies on the instrument's capability to block out the light of the host star.

Deep Space Insights: Machine Learning Revolutionizing Astrophysical Discoveries [PDF]

EPJ Web of Conferences
This paper examines the transformative role of machine learning (ML) in astrophysics. With the exponential growth of astronomical data, traditional methods are often insufficient for effective data management and analysis.

Searching for Giant Exoplanets around M-dwarf Stars (GEMS) I: Survey Motivation

The Astronomical Journal
Recent discoveries of transiting giant exoplanets around M-dwarf stars (GEMS), aided by the all-sky coverage of TESS, are starting to stretch theories of planet formation through the core-accretion scenario.

Revised Architecture and Two New Super-Earths in the HD 134606 Planetary System

The Astronomical Journal
Multiplanet systems exhibit a diversity of architectures that diverge from the solar system and contribute to the topic of exoplanet demographics. Radial velocity (RV) surveys form a crucial component of exoplanet surveys, as their long observational ...

TESS Hunt for Young and Maturing Exoplanets (THYME). XII. A Young Mini-Neptune on the Upper Edge of the Radius Valley in the Hyades Cluster

The Astronomical Journal
We present the discovery and characterization of TOI-4364b, a young mini-Neptune in the tidal tails of the Hyades cluster, identified through TESS transit observations and ground-based follow-up photometry.

Coronagraphic Data Post-processing Using Projections on Instrumental Modes

The Astrophysical Journal
Directly observing exoplanets with coronagraphs is impeded by the presence of speckles from aberrations in the optical path, which can be mitigated in hardware with wave front control, as well as in post-processing. This work explores using an instrument
