ABSTRACT CHEOPS (CHaracterising ExOPlanet Satellite) is an ESA S-class mission that observes bright stars at high cadence from low-Earth orbit. The main aim of the to characterize exoplanets transit nearby using ultrahigh precision photometry. Here, we report analysis transits observed by during its Early Science observing programme for four well-known exoplanets: GJ 436 b, HD 106315 97658 and ...

Context. Observations of the phase curves and secondary eclipses extrasolar planets provide a window onto composition thermal structure planetary atmospheres. For example, photometric observations lead to measurement geometric albedo, A g , which is an indicator presence clouds in atmosphere. Aims. In this work, we aim measure optical domain WASP-43b, moderately irradiated giant planet with equ...

Context. The detection of a super-Earth and three mini-Neptunes transiting the bright ( V = 9.2 mag) star HD 108236 (also known as TOI-1233) was recently reported on basis TESS ground-based light curves. Aims. We perform first characterisation planetary system through high-precision CHEOPS photometry improve transit ephemerides parameters. Methods. characterise host spectroscopic analysis deriv...

in this study, the aim was the evaluation of effect of intravenous (iv) administration of ketamine, peritonsillar infiltration of tramadol and their combination for control of post-operative pain in comparison with single use of each drug in children undergoing tonsillectomy. one hundred and twenty children, aged 2-15 years, selected for elective adenotonsillectomy were enrolled in the study. w...

conclusions this study showed that administration of oral acetaminophen 30 minutes preoperatively, resulted in significantly lower pain intensity in children undergoing adenotonsillectomy in pacu and ward, compared to ibuprofen and placebo. results the average pain intensities were significantly lower in acetaminophen group based on the cheops in both pacu and ward compared to ibuprofen or plac...

Space-based telescopes offer unparalleled opportunities for characterising exoplanets, Solar System bodies and stellar objects. However, observatories in low Earth orbits (e.g. Hubble, CHEOPS, Twinkle an ever increasing number of cubesats) cannot always be continuously pointed at a target due to obscuration. For exoplanet observations consisting transit, or eclipse, spectroscopy this causes gap...

ABSTRACT The accuracy of theoretical mass, radius, and effective temperature values for M-dwarf stars is an active topic debate. Differences between observed have raised the possibility that current stellar structure evolution models are inaccurate towards low-mass end main sequence. To explore this issue, we use CHEOPS satellite to obtain high-precision light curves eclipsing binaries with com...

Abstract The Transiting Exoplanet Survey Satellite (TESS) mission has enabled discoveries of the brightest transiting planet systems around young stars. These are benchmarks for testing theories planetary evolution. We report discovery a mini-Neptune bright star in AB Doradus moving group. HIP 94235 (TOI-4399, TIC 464646604) is V mag = 8.31 G-dwarf hosting <?CDATA ${3.00}_{-0.28}^{+0.32}\,{R}_{...

The study aimed at identifying a scheme of dimensional and geometric relation-ships that could applied to famous megalithic monument called “calendar circle”, located in the archaeological area Nabta Playa. In revealed sizes, there are repetitions some prime numbers. A special role all these cases belongs number 37, which may be is connected with sequence numbers “Dome Algorithm” (1, 2, 3, 5, 7...

BACKGROUND Emergence delirium (ED) is a frequent postoperative complication in young children undergoing ENT procedures and it may be exacerbated by sevoflurane anesthesia whereas propofol maintenance has been suggested to decrease the incidence of ED. The aim of this randomized, prospective, double-blind study was to evaluate the effect of sevoflurane vs propofol anesthesia on the quality of r...
