Abstract The Transit Timing Variation (TTV) technique is a powerful dynamical tool to measure exoplanetary masses by analysing transit light curves. We assessed the timing performances of Ariel Fine Guidance Sensors (FGS1/2) based on simulated curve bright, 55 Cnc, and faint, K2-24, planet-hosting star. estimated through Markov-Chain Monte-Carlo analysis time uncertainty at nominal cadence 1 se...

The transit timing variation (TTV) and transmission spectroscopy analyses of the planet HAT-P-37b, which is a hot Jupiter orbiting an G-type star, were performed. Nine new light curves are obtained analysed together with 21 published from literature. updated physical parameters HAT-P-37b presented. TTV show possibility that system has additional induced TTVs amplitude signal 1.74 $\pm$ 0.17 min...

Myco-like viruses have been isolated from fungi, feces of various animals, and plant leaves. We report here the isolation of 3 complete genome sequences of gemycircularvirus-related viruses from healthy bovine serum and human brain and serum samples from patients with multiple sclerosis (MS). Their putative capsid proteins share similarity to Torque teno virus (TTV) open reading frame 1 (ORF1) ...

Although the top quark was discovered almost ten years ago [1,2], many of its properties are still only poorly known [3]. In particular, the couplings of the top quark to the electroweak (EW) gauge bosons have not yet been directly measured. Current data provide only weak constraints on the couplings of the top quark with the EW gauge bosons, except for the ttZ vector and axial vector couplings...
