Kepler-16b: safe in a resonance cell
, 2013 The planet Kepler-16b is known to follow a circumbinary orbit around a system of two main-sequence stars. We construct stability diagrams in the "pericentric distance - eccentricity" plane, which show that Kepler-16b is in a hazardous vicinity to the ...

Hidden No More: Spotlight on Tidal Disruption Events in Active Galactic Nuclei
Astronomische Nachrichten, EarlyView.ABSTRACT Tidal disruption events (TDEs) are typically discovered in previously quiescent galaxies. However, earlier studies have revealed a handful of TDEs occurring in pre‐existing active galactic nuclei (AGN). We discuss AT2019aalc, a promising TDE candidate in an AGN, and compare it to similar sources.

A Search for Lost Planets in the Kepler Multi-planet Systems and the Discovery of the Long-period, Neptune-sized Exoplanet Kepler-150 f [PDF]
, 2017 The vast majority of the 4700 confirmed planets and planet candidates discovered by the Kepler mission were first found by the Kepler pipeline. In the pipeline, after a transit signal is found, all data points associated with those transits are removed ...

Corporate Environmental Responsibility and Cost of Equity Capital: A Meta‐Analytical Review
Business Strategy and the Environment, EarlyView.ABSTRACT Despite extensive research on the relationship between corporate environmental responsibility (CER) and cost of equity capital (COEC), empirical evidence remains inconsistent. This study addresses these inconsistencies through a comprehensive meta‐analysis of 1139 effect sizes from 75 studies.

Polka-dotted Stars. II. Starspots and Obliquities of Kepler-17 and Kepler-63
The Astrophysical JournalStarspots trace stellar magnetic activity and affect both stellar evolution and exoplanet characterization. While occultation-based spot studies have been applied to individual systems, comparative analyses remain limited.

ALGEBRAIC DESCRIPTION OF SHAPE INVARIANCE REVISITED
Acta Polytechnica, 2017 We revisit the algebraic description of shape invariance method in one-dimensional quantum mechanics. In this note we focus on four particular examples: the Kepler problem in flat space, the Kepler problem in spherical space, the Kepler problem in ...

They might be giants: luminosity class, planet frequency, and planet-metallicity relation of the coolest Kepler target stars [PDF]
, 2012 We estimate the stellar parameters of late K and early M type Kepler target stars. We obtain medium resolution visible spectra of 382 stars with Kp-J>2 (~K5 and later spectral type).

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.Abstract Purpose Injuries to the knee are common in elite athletes and often involve damage to the articular cartilage. Given the high demands of elite sport, full‐thickness articular cartilage defects in the knee can be career‐limiting or threatening.
