The Triple System V1371 Tau: An Eclipsing Binary with an Outer Be Star

The Astrophysical Journal
Although triple systems are common, their orbital dynamics and stellar evolution remain poorly understood. We investigated the V1371 Tau system using TESS photometry, multiepoch spectroscopy, and recent interferometric data, confirming it as a rare ...

The massive binary population of the starburst cluster Westerlund 1 [PDF]

, 2010
We present initial results from a long-baseline radial velocity survey for massive binaries in the cluster Westerlund 1. Four systems are examined: the dust-producing WC binary W239, the double-lined eclipsing binary W13, and the single-lined B0 ...

Punchline with(out) purpose: Integrating research on instructional humour and seductive details

British Journal of Educational Psychology, EarlyView.
Abstract Introduction We integrated research on instructional humour and seductive details to investigate when affiliative course‐related humour is effective or rather ineffective for learning. We assumed that instructional humour without a cognitive function (irrelevant humour) would have detrimental effects on learning performance resembling the ...

EVOLUTIONARY EFFECTS IN CLOSE BINARIES: ANALYSIS OF THE DISTRIBUTION OF ORBITAL ECCENTRICITIES

Odessa Astronomical Publications, 2017
Dependencies of orbital eccentricity e on orbital periods P in close binary systems (CBS) of different masses and ages, being at the Main Sequence (DMS) and being eclipsing binary stars (EBS), are reviewed.

Phenomenological modelling of eclipsing system light curves

, 2015
The observed light curves of most eclipsing binaries and stars with transiting planets can be well described and interpreted by current advanced physical models which also allow for the determination of many physical parameters of eclipsing systems ...

Relationship Between PTBP1 and Pancreatic Cancer Based on microRNA and Behavior During TYMS‐Mediated Carcinogenesis

Cancer Science, EarlyView.
Corresponding Author and colleagues identify a pancreas‐enriched microRNA, miR‐216b‐5p, that suppresses PTBP1 and its downstream effector TYMS. Their findings reveal a novel miR‐216b‐5p/PTBP1/TYMS regulatory axis driving pancreatic cancer progression and establish PTBP1 as a central molecular regulator of tumor biology beyond its metabolic role ...

A Reflection Model for Eclipsing Binary Stars [PDF]

Monthly Notices of the Royal Astronomical Society, 1973
A highly accurate reflection model has been developed which emphasizes efficiency of computer calculation. It is assumed that the heating of the irradiated star must depend upon the following properties of the irradiating star: (1) effective temperature; (2) apparent area as seen from a point on the surface of the irradiated star; (3) limb darkening ...

TIC 290061484: A Triply Eclipsing Triple System with the Shortest Known Outer Period of 24.5 Days

The Astrophysical Journal
We have discovered a triply eclipsing triple-star system, TIC 290061484, with the shortest known outer period, P _out , of only 24.5 days. This “eclipses” the previous record set by λ Tauri at 33.02 days, which held for 68 yr.

Association of Fontan Circulation With Gut Microbiome Derived Straight and Branched Short Chain Fatty Acids

Journal of Gastroenterology and Hepatology, EarlyView.
Adults with Fontan circulation (n = 20) and matched controls underwent body composition, frailty testing, CPET, and NICaS hemodynamics. Plasma short‐chain fatty acids were quantified by LC–MS/MS. Fontan patients had higher straight and branched SCFAs, correlating with lower muscle mass, greater frailty, reduced VO2max, and worse resting/postexercise ...

Precision Timing of Eclipsing Binaries from TESS Full Frame Images: Method and Performance

The Astrophysical Journal
Several hundreds of thousands of eclipsing binaries (EBs) are expected to be detected in the Transiting Exoplanet Survey Satellite (TESS) full frame images (FFIs).
