The K2 and TESS Synergy. I. Updated Ephemerides and Parameters for K2-114, K2-167, K2-237, and K2-261 [PDF]

The Astronomical Journal, 2020
Abstract Although the Transiting Exoplanet Survey Satellite (TESS) primary mission observed the northern and southern ecliptic hemispheres, generally avoiding the ecliptic, and the Kepler space telescope during the K2 mission could only observe near the ecliptic, many of the K2 fields extend far enough from the ecliptic plane that ...

K2-60b and K2-107b. A Sub-Jovian and a Jovian Planet from the K2 Mission [PDF]

The Astronomical Journal, 2017
Abstract We report the characterization and independent detection of K2-60b, as well as the detection and characterization of K2-107b, two transiting hot gaseous planets from the K2 space mission. We confirm the planetary nature of the two systems and determine their fundamental parameters combining the K2 time-series data with FIES@NOT ...

K2-114b and K2-115b: Two Transiting Warm Jupiters [PDF]

The Astronomical Journal, 2017
Abstract We report the first results from a search for transiting warm Jupiter exoplanets—gas giant planets receiving stellar irradiation below about 108 erg s−1 cm−2, equivalent to orbital periods beyond about 10 days around Sun-like stars.

K2-140b and K2-180b – Characterization of a hot Jupiter and a mini-Neptune from theK2mission [PDF]

Monthly Notices of the Royal Astronomical Society, 2018
We report the independent discovery and characterization of two K2 planets: K2-180b, a mini-Neptune-size planet in an 8.9-day orbit transiting a V = 12.6 mag, metal-poor ([Fe/H] =$-0.65\pm0.10$) K2V star in K2 campaign 5; K2-140b, a transiting hot Jupiter in a 6.6-day orbit around a V = 12.6 mag G6V ([Fe/H] = $+0.10\pm0.10$) star in K2 campaign 10.

Scaling K2. V. Statistical Validation of 60 New Exoplanets From K2 Campaigns 2–18 [PDF]

The Astronomical Journal, 2022
The NASA K2 mission, salvaged from the hardware failures of the Kepler telescope, has continued Kepler’s planet-hunting success. It has revealed nearly 500 transiting planets around the ecliptic plane, many of which are the subject of further study, and ...

Disproving the validated planets K2-78b, K2-82b, and K2-92b [PDF]

Astronomy & Astrophysics, 2017
Context. Transiting super-Earths orbiting bright stars in short orbital periods are interesting targets for the study of planetary atmospheres. Aims. While selecting super-Earths suitable for further characterisation from the ground from a list of confirmed and validated exoplanets detected by K2, we found some suspicious cases that led to us ...

K2-295 b and K2-237 b: two transiting hot Jupiters [PDF]

Acta Astronomica, 2018
We report the discovery from K2 of two transiting hot Jupiter systems. K2-295 (observed in Campaign 8) is a K5 dwarf which hosts a planet slightly smaller than Jupiter, orbiting with a period of 4.0 d. We have made an independent discovery of K2-237 b (Campaign 11), which orbits an F6 dwarf every 2.2 d and has an inflated radius 50 - 60 per cent larger

Mandatory audit rotation and audit market concentration—evidence from Poland

Economics and Business Review, 2019
The new audit regulation came into force in Poland in 2017 and imposed mandatory audit rotation. The new regulation aims to strengthen the auditor’s independence but it might also affect concentration on the audit market.
