We present a catalog of distances for 19544 K-giants drawn from Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) DR8. Most of them are located in the halo of...

Gliese86 is a nearby K-dwarf hosting a giant planet on a ~16day orbit and an outer white dwarf companion on a ~century-long orbit. In this study we combine radial velocity data...

We report helium absorption from the escaping atmosphere of TOI560.01 (HD73583b), an R=2.8R{Earth}, P=6.4day mini-Neptune orbiting a young (~600Myr) K-dwarf. Using Keck/NIRSPEC,...

Multiplanet systems are valuable arenas for investigating exoplanet architectures and comparing planetary siblings. TOI-1246 is one such system, with a moderately bright K-dwarf...

We report the discovery of a highly eccentric long-period Jovian planet orbiting the hot-Jupiter host HD83443. By combining radial velocity data from four instruments...

The distortions of absorption line profiles caused by photospheric brightness variations on the surfaces of cool, main-sequence stars can mimic or overwhelm radial velocity (RV)...

We report the discovery of HIP-97166b (TOI-1255b), a transiting sub-Neptune on a 10.3day orbit around a K0 dwarf 68pc from Earth. This planet was identified in a systematic...

Giant stars as known exoplanet hosts are relatively rare due to the potential challenges in acquiring precision radial velocities and the small predicted transit depths....

We report initial results of a large radial velocity survey of K dwarfs up to a distance of 50pc from the solar system, to look for stellar, brown dwarf, and Jovian planets...

Since the launch of the Kepler space telescope in 2009 and the subsequent K2 mission, hundreds of multiplanet systems have been discovered. The study of such systems, both as...

We present the discovery of two planets orbiting the nearby (D=11.9pc) K7 dwarf Gl414A. Gl414Ab is a sub-Neptune mass planet with M_b_sini_b_=7.60_-2.19_^+2.44^M{Earth} and a...

With a mass in the Neptune regime and a radius of Jupiter, WASP-107b presents a challenge to planet formation theories. Meanwhile, the planet's low surface gravity and the...

We report the discovery by the ground-based Hungarian-made Automated Telescope Network (HATNet) survey of the transiting exoplanet HAT-P-68b, which has a mass of...

This paper details speckle observations of binary stars taken at the Lowell Discovery Telescope, the WIYN telescope, and the Gemini telescopes between 2016 January and 2019...

We report the discovery of four transiting giant planets around K-dwarfs. The planets HATS-47b, HATS-48Ab, HATS-49b, and HATS-72b have masses of 0.369_-0.021_^+0.031^M_J_,...

We present the most sensitive direct imaging and radial velocity (RV) exploration of {epsilon} Eridani to date. {epsilon} Eridani is an adolescent planetary system, reminiscent...

HAT-P-11 is a mid-K dwarf that hosts one of the first Neptune-sized planets found outside the solar system. The orbit of HAT-P-11b is misaligned with the star's spin-one of the...

We present a catalog of cool dwarf targets (V-J>2.7, T_eff_~<4000 K) and their stellar properties for the upcoming Transiting Exoplanet Survey Satellite (TESS), for the...

We report the discovery of a radial velocity signal that can be interpreted as a planetary-mass candidate orbiting the K dwarf HD 26965, with an orbital period of 42.364+/-0.015...

HD 3167 is a bright (V=8.9 mag) K0 V star observed by NASA's K2 space mission during its Campaign 8. It has recently been found to host two small transiting planets, namely, HD...
