Improved parameters of seven Kepler giant companions characterized with SOPHIE and HARPS-N [PDF]
A&A 575, A85 (2015), 2015 Radial-velocity observations of Kepler candidates obtained with the SOPHIE and HARPS-N spectrographs have permitted unveiling the nature of the five giant planets Kepler-41b, Kepler-43b, Kepler-44b, Kepler-74b, and Kepler-75b, the massive companion ...

Lorentz Group and Oriented MICZ-Kepler Orbits [PDF]
J. Math. Phys. 53, 052901 (2012), 2011 The MICZ-Kepler orbits are the non-colliding orbits of the MICZ Kepler problems (the magnetized versions of the Kepler problem). The oriented MICZ-Kepler orbits can be parametrized by the canonical angular momentum $\mathbf L$ and the Lenz vector ...

No timing variations observed in third transit of snow-line exoplanet Kepler-421b [PDF]
, 2016 We observed Kepler-421 during the anticipated third transit of the snow-line exoplanet Kepler-421b in order to constrain the existence and extent of transit timing variations (TTVs).

Gravitational quantization of exoplanet orbits in HD 10180, Kepler-32, Kepler-33, Kepler-102, and Kepler-186 [PDF]
arXiv, 2015 The so-called "global polytropic model" is applied to the numerical study of the exoplanet systems HD 10180, Kepler-32, Kepler-33, Kepler-102, and Kepler-186. We compare computed distances of planets from their host stars with corresponding observations and discuss some further orbit predictions made by the model.

TESS Observations of Kepler systems with Transit Timing Variations [PDF]
AJ, 164, 42J (2022), 2022 We identify targets in the Kepler field that may be characterized by transit timing variations (TTVs) and are detectable by the Transiting Exoplanet Survey Satellite (TESS). Despite the reduced signal-to-noise ratio of TESS transits compared to Kepler, we recover 48 transits from 13 systems in Sectors 14, 15, 26, 40 and 41. We find strong evidence of a

Astronomische Nachrichten, Volume 343, Issue 9-10, November-December 2022., 2022 Abstract The advent of ultra‐precise photometry space missions enables the possibility of investigating stellar interiors with mixed modes. The structural variations induced by the discontinuity of the chemical composition left behind during the first dredge–up is an important feature in the stellar mid‐layers located between the hydrogen‐burning shell

Cancer, Volume 129, Issue 3, Page 426-440, 1 February 2023., 2023 Abstract Background Survivors of Hodgkin lymphoma (HL) are at risk of developing non‐Hodgkin lymphoma (NHL) after treatment; however, the risks of developing subsequent primary lymphomas (SPLs), including HL and NHL, after different types of childhood cancer are unknown.

On the regularization of the Kepler problem [PDF]
Journal of Symplectic Geometry, 2012 We show that for the Kepler problem the canonical Ligon-Schaaf regularization map can be understood in a straightforward manner as an adaptation of the Moser regularization. In turn this explains the hidden symmetry in a geometric way.

Kepler-102: Masses and Compositions for a Super-Earth and Sub-Neptune Orbiting an Active Star
The Astronomical Journal, 2023 Radial velocity (RV) measurements of transiting multiplanet systems allow us to understand the densities and compositions of planets unlike those in the solar system. Kepler-102, which consists of five tightly packed transiting planets, is a particularly
