Surprise Nondetection of Upsilon Andromedae b with MIRC-X and MYSTIC at the CHARA Array

The Astronomical Journal
Ground-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

Saturns, but Not Super-Jupiters, Occur More Frequently in the Presence of Inner Super-Earths

The Astrophysical Journal
Studies from recent years have reached different conclusions regarding how frequently super-Earths are accompanied by long-period giant planets and vice versa. This relation has been predicted to be mass dependent by planet-formation models.

TESS Discovery of an ultra-short-period planet around the nearby M dwarf LHS 3844

, 2018
Data from the newly-commissioned \textit{Transiting Exoplanet Survey Satellite} (TESS) has revealed a "hot Earth" around LHS 3844, an M dwarf located 15 pc away.

Minimizing Star-spot Contamination of Exoplanet Transit Spectroscopy Using Alternate Normalization

The Astronomical Journal
Recently, M. H. Currie et al. (2023) simulated the detection of molecules in the atmospheres of temperate rocky exoplanets transiting nearby M-dwarf stars.

UNH Observatory Exoplanet Transit Depth Limit [PDF]

, 2019
Using the University of New Hampshire Observatory, we performed multiple exoplanet transits observations on a variety of systems. Of these transits, those performed with ideal weather conditions were chosen to do extensive analysis on. The transit chosen

The three-body problem

, 2014
The three-body problem, which describes three masses interacting through Newtonian gravity without any restrictions imposed on the initial positions and velocities of these masses, has attracted the attention of many scientists for more than 300 years ...

Ruling Out Possible Secondary Stars to Exoplanet Host Stars Using the CHARA Array

, 2010
Of the over 450 exoplanets known to date, more than 420 of them have been discovered using radial velocity studies, a method that tells nothing about the inclination of the planet's orbit.

Astronomy from the moon in the next decades: from exoplanets to cosmology in visible light and beyond

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences
We look at what astronomy from the Moon might be like over the next few decades. The Moon offers the possibility of installing large telescopes or interferometers with instruments larger than those on orbiting telescopes. We first present examples of ambitious science cases, in particular ideas that cannot be implemented from Earth.

Comparing Results from Two Uniform Phase-curve Surveys

The Astronomical Journal
We present a comparison of the two most recent and comprehensive Spitzer phase curve studies—L. Dang et al. and M. R. Swain et al.—which report analyses of the Spitzer 4.5 μ m phase curves.
