We present results of an extensive investigation of the physical changes taking place in the emission regions of the LMXB X 1624-490 during strong flaring in observations made using RXTE in 1997 and 1999. Based on the detailed light curve, we propose that the flaring consists of a superposition of X-ray bursts. It is shown that major changes take place in the blackbody emission component, the t...

The extreme space weather conditions resulting from high energetic events likes solar flares and Coronal Mass Ejections demand for reliable forecasting. magnetic flux tubes while rising through the convection zone gets twisted by turbulent plasma flows, energizing system in flares. We investigate relationship between subsurface flows associated with flaring active regions their surface current ...

We present high-resolution observations of a flaring event in the M8 dwarf vB 10 using near-infrared Habitable zone Planet Finder (HPF) spectrograph on Hobby Eberly Telescope (HET). The high stability HPF enables us to accurately subtract VB quiescent spectrum from flare isolate contributions, and study changes relative energy Ca II infrared triplet (IRT), several Paschen lines, He 10830 \AA~ s...

Small scale transients occur in the Solar corona at much higher frequencies than flares and play a significant role coronal dynamics. Here we study three well-identified discovered by Hi-C also detected EUV channels of Atmospheric Imaging Assembly (AIA) on board Dynamics Observatory (SDO). We use 0-D enthalpy-based hydrodynamical simulations produce synthetic light curves to compare with AIA ob...

Reported here are primary avian geographical records for the nation of Peru and for the western declivity of the Peruvian Andes. Not previously encountered anywhere in Peru is Myrmeciza exsul (Chestnut-backed Antbird), a periorbitally blue thamnophilid possessing apically maculate tectrices. This species was observed on the western inclination of the Andean Mountains in Peru. Recorded primally ...

Context. Following a multi-year minimum of solar activity, energetic particle event on 2020 Nov. 29 was observed by multiple spacecraft covering wide range longitudes including ACE, the Solar Terrestrial Relations Observatory-A, and recently launched Parker Probe Orbiter. Aims. Multi-point observations event, combined with remote-sensing imaging flaring, shocks, coronal mass ejections allows fo...

  Background: To determine the most important preoperative factors that affect postoperative coronal parameters of scoliotic curves.   Methods: All Adolescent Idiopathic Scoliosis (AIS) patients included in the study were classified according to Lenke and King Classification. The fusion levels were selected according to the rigidity of the existing curves (correction less than 50%), tilt...

The uniqueness and stability of irradiated flaring passive protostellar disks is investigated in the context of a simplified set of equations for the vertical height H as a function of radius R. It is found that the well-known flaring disk solution with H ∝ R9/7 is not unique. Diverging solutions and asymptotically conical (H ∝ R) solutions are also found. Moreover, using time-dependent linear ...

A set of methods are presented for the global survey of natural gas flaring using data collected by the National Aeronautics and Space Administration/National Oceanic and Atmospheric Administration NASA/NOAA Visible Infrared Imaging Radiometer Suite (VIIRS). The accuracy of the flared gas volume estimates is rated at ̆9.5%. VIIRS is particularly well suited for detecting and measuring the radia...

BACKGROUND Long-pulsed Nd : YAG laser has been used in treating larger and deep-seated leg veins. OBJECTIVE This study investigated the effectiveness and safety of long-pulsed Nd : YAG laser to treat alae nasae and nasal tip telangiectasia. METHODS Twelve patients were evaluated in a prospective IRB approved study. They had a history of previous unsatisfactory treatments with pulsed dye las...
