An extremely low-density and temperate giant exoplanet

A. Santerne, L. Malavolta, M. R. Kosiarek +68

Transiting extrasolar planets are key objects in the study of the formation, migration, and evolution of planetary systems. In particular, the exploration of the atmospheres of gia…

Radial Velocity Discovery of an Eccentric Jovian World Orbiting at 18 au

Sarah Blunt, Michael Endl, Lauren M. Weiss +25

Based on two decades of radial velocity (RV) observations using Keck/HIRES and McDonald/Tull, and more recent observations using the Automated Planet Finder, we found that the near…

A super-Earth and sub-Neptune transiting the late-type M dwarf LP 791-18

Ian J. M. Crossfield, William Waalkes, Elisabeth R. Newton +57

Planets occur most frequently around cool dwarfs, but only a handful of specific examples are known to orbit the latest-type M stars. Using TESS photometry, we report the discovery…

Discovery of a White Dwarf Companion to HD 159062

Lea A. Hirsch, David R. Ciardi, Andrew W. Howard +11

We report on the discovery of a white dwarf companion to the nearby late G dwarf star, HD 159062. The companion is detected in 14 years of precise radial velocity (RV) data, and in…

The Type II-Plateau Supernova 2017eaw in NGC 6946 and Its Red Supergiant Progenitor

Schuyler D. Van Dyk, WeiKang Zheng, Justyn R. Maund +31

We present extensive optical photometric and spectroscopic observations, from 4 to 482 days after explosion, of the Type II-plateau (II-P) supernova (SN) 2017eaw in NGC 6946. SN 20…

Long-Period Giant Companions to Three Compact, Multiplanet Systems

Sean M. Mills, Andrew W. Howard, Lauren M. Weiss +7

Understanding the relationship between long-period giant planets and multiple smaller short-period planets is critical for formulating a complete picture of planet formation. This…

K2-291 b: A rocky super-Earth in a 2.2 day orbit

Molly R. Kosiarek, Sarah Blunt, Mercedes Lopez-Morales +43

K2-291 (EPIC 247418783) is a solar-type star with a radius of R_star = 0.899 0.034 R_sun and mass of M_star=0.934 0.038 M_sun. From K2 C13 data, we found one super-Eart…

K2-288Bb: A Small Temperate Planet in a Low-mass Binary System Discovered by Citizen Scientists

Adina D. Feinstein, Joshua E. Schlieder, John H. Livingston +23

Observations from the Kepler and K2 missions have provided the astronomical community with unprecedented amounts of data to search for transiting exoplanets and other astrophysical…

Spitzer transit follow-up of planet candidates from the K2 mission

John H. Livingston, Ian J. M. Crossfield, Michael W. Werner +21

We present precision 4.5 m Spitzer transit photometry of eight planet candidates discovered by the K2 mission: K2-52 b, K2-53 b, EPIC 205084841.01, K2-289 b, K2-174 b, K2-87 b,…
