Revised Architecture and Two New Super-Earths in the HD 134606 Planetary System
The Astronomical JournalMultiplanet 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 ...

Coronagraphic Data Post-processing Using Projections on Instrumental Modes
The Astrophysical JournalDirectly 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

Accounting for Transit Timing Detectability: Biases in Planetary Radius and Orbital Period
The Astronomical JournalTransit Timing Variations (TTVs) are deviations from the time an observer would expect to see an exoplanet transit its host star. In multiplanetary systems, significant TTVs may indicate the presence of another body in the system gravitationally ...

TOI-6695: A Pair of Near-resonant Massive Planets Observed with TESS from the WINE Survey
The Astronomical JournalWe present the discovery and characterization of a pair of warm Jovian-mass exoplanets orbiting the Sun-like star TOI-6695, based on Transiting Exoplanet Survey Satellite (TESS) transits and precise radial velocity (RV) measurements obtained with FEROS ...
