With the launch of the JWST, we will obtain more precise data for exoplanets than ever before. However, these data can only inform and revolutionize our understanding of...

We present the discovery of a new Jovian-sized planet, TOI-3757b, the lowest-density transiting planet known to orbit an M dwarf (M0V). This planet was discovered around a...

Only a handful of late T brown dwarfs have been monitored for spectrophotometric variability, leaving incomplete the study of the atmospheric cloud structures of the coldest...

Phosphorus (P) is a critical element for life on Earth, yet the cosmic production sites of P are relatively uncertain. To understand how P has evolved in the solar neighborhood,...

Orbiting an M dwarf 12pc away, the transiting exoplanet GJ1132b is a prime target for transmission spectroscopy. With a mass of 1.7M{Earth} and radius of 1.1R{Earth}, GJ1132b's...

The recently rediscovered open cluster Stock2, located roughly 375pc away and about 400Myr old, has the potential to be an exciting new testbed for our understanding of stellar...

We study the kinematics of emission lines that arise from many physical processes in NGC6153 based upon deep, spatially resolved, high-resolution spectra acquired with the UVES...

The photometric and spectral variability of brown dwarfs probes heterogeneous temperature and cloud distributions and traces the atmospheric circulation patterns. We present a...

We investigate the nature of an unusually faint member of the {epsilon}Cha association (D~100pc, age ~5Myr), the nearest region of star formation of age <8Myr. This object,...

In this paper, we present Transiting Exoplanet Survey Satellite (TESS) photometry and high-resolution spectra of the short-period Algol-EW-Boo. We obtained double-lined radial...

The coevolution of T-Tauri stars and their surrounding protoplanetary disks dictates the timescales of planet formation. In this paper, we present magnetospheric accretion and...

Low- and intermediate-mass (0.8M{sun}

We present an overview and first results from a M-band spectroscopic survey of planet-forming disks performed with iSHELL on the Infrared Telescope Facility, using two slits...

The Kepler mission revealed a class of planets known as "super-puffs," with masses only a few times larger than Earth's but radii larger than Neptune, giving them very low mean...

The collections of spectral energy distributions (SEDs) in the Hubble Space Telescope (HST) CALSPEC database are augmented by 19 infrared (IR) SEDs from Wide Field Camera 3...

Results of observations with the Spitzer, Hubble, GALEX, Chandra, and XMM-Newton space telescopes are presented for the luminous infrared galaxy (LIRG) merger Markarian 266. The...

We are continuing a J, K and narrowband imaging survey of 300{deg}^2^ of the plane of the Galaxy, searching for new Wolf-Rayet (W-R) stars. Our survey spans 150{deg} in Galactic...

The absolutely calibrated infrared (IR) stellar spectra of standard stars described by Engelke et al. are being extended into the visible and will span a continuous wavelength...

We present a brief atlas of L-band (3.3-4.2um) spectra for 42 stars plus the Sun and a sunspot observed at a resolving power of R~3000. This contribution is intended to...

The Point Source Infrared Sky Model of Wainscoat et al. [ApJS, 83, 111 (1992)] is extended to make predictions for any filter lying wholly within the range 2.0 to 35.0 microns....
