We present the discovery of a transiting exoplanet candidate in the K2 Field-1 with an orbital period of 9.1457 hr: K2-22b. The highly variable transit depths, ranging from ∼0% to 1.3%, are suggestive of a planet that is disintegrating via the emission of dusty effluents. We characterize the host star as an M-dwarf with Teff ≃ 3800 K. We have obtained ground-based transit measurements with several 1-m class telescopes and with the GTC. These observations (1) improve the transit ephemeris; (2…

CHARACTERIZATION OF THE K2-19 MULTIPLE-TRANSITING PLANETARY SYSTEM VIA HIGH-DISPERSION SPECTROSCOPY, AO IMAGING, AND TRANSIT TIMING VARIATIONS

K2-19 (EPIC201505350) is an interesting planetary system in which two transiting planets with radii ∼7 R⊕ (inner planet b) and ∼4 R⊕ (outer planet c) have orbits that are nearly in a 3:2 mean-motion

The K2-ESPRINT project. VI. K2-105 b, a hot Neptune around a metal-rich G-dwarf

We report on the confirmation that the candidate transits observed for the star EPIC 211525389 are due to a short-period Neptune-sized planet. The host star, located in K2 campaign field 5, is a

A Possible Transit of a Disintegrating Exoplanet in the Nearby Multiplanet System DMPP-1

We analyze TESS photometry of DMPP-1 (HD 38677; TIC 66560666), a nearby F8V star hosting hot super-Earth planets and a warm Neptune. Using the Transit Least Squares algorithm and other methods we

THE K2-ESPRINT PROJECT. II. SPECTROSCOPIC FOLLOW-UP OF THREE EXOPLANET SYSTEMS FROM CAMPAIGN 1 OF K2

We report on Doppler observations of three transiting planet candidates that were detected during Campaign 1 of the K2 mission. The Doppler observations were conducted with FIES, HARPS-N, and HARPS.

Back to “Normal” for the Disintegrating Planet Candidate KIC 12557548 b

KIC 12557548 b is the first of a growing class of intriguing disintegrating planet candidates, which lose mass in the form of a metal-rich vapor that condenses into dust particles. Here, we follow up

A Large Ground-based Observing Campaign of the Disintegrating Planet K2-22b

We present 45 ground-based photometric observations of the K2-22 system collected between 2016 December and 2017 May, which we use to investigate the evolution of the transit of the disintegrating

Likely Transiting Exocomets Detected By Kepler.

TLDR
The first good evidence for exocomet transits of a host star in continuum light in data from the Kepler mission is presented, and a single comet-shaped transit is found in KIC 11084727 with very similar transit and host-star properties.
