Extant interspecific hybridization among trematodes within the Schistosoma haematobium species complex in Nigeria. [PDF]

open access: yesPLoS Neglected Tropical Diseases
BackgroundNatural interspecific hybridization between the human parasite (Schistosoma haematobium [Sh]) and bovine parasites (Schistosoma bovis [Sb], Schistosoma curassoni [Sc]) is increasingly reported in Africa.

The Apparent Tidal Decay of WASP-4 b Can Be Explained by the Rømer Effect

open access: yesUniverse, 2023
Tidal orbital decay plays a vital role in the evolution of hot Jupiter systems. As of now, this has only been observationally confirmed for the WASP-12 system.

Transiting Circumbinary Planets in the Era of Space-Based Photometric Surveys

open access: yesUniverse, 2023
Planets orbiting binary stars—circumbinary planets—play a paramount role in our understanding of planetary and stellar formation and evolution, dynamical interactions in many-body systems, and the potential for habitable environments beyond the Solar ...

Orbital Period Refinement of CoRoT Planets with TESS Observations

open access: yesFrontiers in Astronomy and Space Sciences, 2021
CoRoT was the first space mission dedicated to exoplanet detection. Operational between 2007 and 2012, this mission discovered 37 transiting planets, including CoRoT-7b, the first terrestrial exoplanet with a measured size. The precision of the published

Characterization of a Set of Small Planets with TESS and CHEOPS and an Analysis of Photometric Performance

open access: yesThe Astronomical Journal, 2023
The radius valley carries implications for how the atmospheres of small planets form and evolve, but this feature is visible only with highly precise characterizations of many small planets.

The Breakthrough Listen Search for Intelligent Life: Detection and Characterization of Anomalous Transits in Kepler Lightcurves

open access: yesThe Astronomical Journal, 2023
Never before has the detection and characterization of exoplanets via transit photometry been as promising and feasible as it is now, due to the increasing breadth and sensitivity of time domain optical surveys.

Comparison of visual and acoustic surveys for the detection and dynamic management of North Atlantic right whales (Eubalaena glacialis) in Canada

open access: yesConservation Science and Practice, 2023
The goal of this study was to develop a simulation to quantitatively compare acoustic and visual surveys and use it to inform current and future North Atlantic right whale (Eubalaena glacialis) risk mitigation.

The study of exoplanets and protoplanetary discs in the Main astronomical observatory of NAS of Ukraine

open access: yesВісник Астрономічної школи, 2016
Long-term spectral and photometric observations of transit and nontransit exoplanet systems are carried out in MAO NAS of Ukraine. On the base of obtained data we study the influence of exoplanets on chromospherical activity of the host stars, model the ...

Gifts from Exoplanetary Transits [PDF]

open access: yes, 2009
The discovery of transiting extrasolar planets has enabled us a number of interesting stduies. Transit photometry reveals the radius and the orbital inclination of transiting planets, and thereby we can learn the true mass and the density of respective ...
