AN INDEPENDENT ANALYSIS OF KEPLER-4b THROUGH KEPLER-8b [PDF]

open access: yesThe Astrophysical Journal, 2011
We present two independent, homogeneous, global analyses of the transit light curves, radial velocities and spectroscopy of Kepler-4b through Kepler-8b, with numerous differences over the previous methods. These include: 1) improved decorrelated parameter fitting set, 2) new limb darkening coefficients, 3) time-stamps modified to BJD for consistency ...

EXOPLANET CHARACTERIZATION BY PROXY: A TRANSITING 2.15RPLANET NEAR THE HABITABLE ZONE OF THE LATE K DWARF KEPLER-61 [PDF]

open access: bronze, 2013
We present the validation and characterization of Kepler-61b: a 2.15 R_Earth planet orbiting near the inner edge of the habitable zone of a low-mass star.

Improved parameters of seven Kepler giant companions characterized with SOPHIE and HARPS-N [PDF]

open access: yes, 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 ...

Characterisation and impact of intratumoural stroma in melanoma and carcinoma brain metastases. [PDF]

open access: yesJ Pathol Clin Res
Abstract Research on the tumour microenvironment in brain metastases (BM) has predominantly focused on the immune response, while the presence, morphological patterns, and potential clinical relevance of intratumoural stroma remain less intensively investigated.

A 38 Million Year Old Neptune-sized Planet in the Kepler Field

open access: yesThe Astronomical Journal, 2022
Kepler 1627A is a G8V star previously known to host a 3.8 R _⊕ planet on a 7.2 day orbit. The star was observed by the Kepler space telescope because it is nearby ( d = 329 pc) and it resembles the Sun.

The McDonald Accelerating Stars Survey: Architecture of the Ancient Five-planet Host System Kepler-444

open access: yesThe Astronomical Journal, 2023
We present the latest and most precise characterization of the architecture for the ancient (≈11 Gyr) Kepler-444 system, which is composed of a K0 primary star (Kepler-444 A) hosting five transiting planets and a tight M-type spectroscopic binary (Kepler-

Kepler-20: A Sun-like Star with Three Sub-Neptune Exoplanets and Two Earth-size Candidates [PDF]

open access: yes, 2011
We present the discovery of the Kepler-20 planetary system, which we initially identified through the detection of five distinct periodic transit signals in the Kepler light curve of the host star 2MASSJ19104752+4220194.

Experiencia estética y formulación científica: el caso del Harmonices Mundi de Johannes Kepler

open access: yesAnuario Musical, 2013
La música como modelo explicativo del universo ha estado presente desde el mismo nacimiento de la reflexión filosófica. En el caso de Kepler, la música y la astronomía quedaban homologadas sobre la base de un único arquetipo geométrico, y por ello podían

The atmospheres of the hot-Jupiters Kepler-5b and Kepler-6b observed during occultations with Warm-Spitzer and Kepler [PDF]

open access: yes, 2011
This paper reports the detection and the measurements of occultations of the two transiting hot giant exoplanets Kepler-5b and Kepler-6b by their parent stars. The observations are obtained in the near infrared with Spitzer Space Telescope and at optical
