SCIENCE: Bizarre Vortex Waves Discovered on The Sun Hint at New Solar Physics.

A new type of high- fre­quence aur­al surge dis­cov­ered prop­a­gat­ing on the Sun seems to be defy­ing expectan­cies.
 
 The waves appear on the face of the Sun as a pat­tern of swirling mael­stroms, mov­ing against the Sun’s gyra­tion. The prob­lem is that these high- fre­quence ret­ro­grade vor­tic­i­ty swells feel to be mov­ing three times faster than fore­cast by the­sis – and solar physi­cists have been inca­pable to deter­mine why.
The dis­cov­ery, they say, sug­gests that there’s new solar reme­dies to be uncov­ered, as well as giv­ing fresh per­cep­tion into the Sun’s inter­nal parcels and exer­tion.
 
 Although we can not actu­al­ly see inside the Sun, stars are remark­able in that their inter­nal process­es can fre­quent­ly be inferred ground­ed on face exer­tion.
In par­tic­u­lar, aur­al swells can tell us a lot. They’re gen­er­at­ed close to the face, and are also reflect­ed, either part­ly or entire­ly, towards the inte­ri­or, where they sound, cre­at­ing acoustic oscil­la­tions. Solar sci­en­tists study these oscil­la­tions to learn about the inside of the Sun.
 
 A crew of sci­en­tists led by solar physi­cist Chris Han­son of New York Uni­ver­si­ty, Abu Dhabi, stud­ied and dis­sect­ed sim­i­lar data, using 24 years of obser­vances from the ground- ground­ed Glob­al Oscil­la­tion Net­work Group, and 10 years of obser­vances from the space- ground­ed Helio­seis­mic and Mag­net­ic Imager.
In the data, the exper­i­menters plant a ver­i­ta­bly har­mo­nious sig­nal, which their analy­sis reveals as the pres­ence of pre­lim­i­nar­i­ly unseen waves. These formed a pat­tern of mael­stroms on the face of the Sun, with an anti­sym­me­try between north and south poles, mov­ing against the solar twirl.
 
 The fact that these waves are mov­ing three times faster than await­ed, still, pos­es a rid­dle. The pla­toon explored a num­ber of pos­si­bil­i­ties for what was going on.
 First, the Cori­o­lis force – the way a rotat­ing glob­u­lar objec­t’s ambit moves faster than its poles – excites vor­tic­i­ty swells, as we know can be then on Earth.
 
 Also, there are three mech­a­nisms that could affect and mod­i­fy the waves mag­net­ism, grave­ness, or con­vec­tion. None of them could regard for the obser­va­tion data, still.
 Still, also the find­ing would have answered some open ques­tions we still have about the Sun,“Hanson says,“If the high- fre­quence ret­ro­grade waves could be attrib­uted to any of these three process­es.
 
” Still, these new waves do not appear to be a result of these process­es, and that is pro­vok­ing because it leads to a whole new set of ques­tions.“
This sug­gests, the researchers say, that there’s miss­ing or bad­ly con­strained infor­ma­tion in our mod­els of the Sun that resolv­ing the rid­dle could fill in.
 
 It also has applic­a­bil­i­ty a bit clos­er to home. Sci­en­tists have plant high- fre­quence waves in the ocean, prop­a­gat­ing up to four times high than prog­nos­ti­cat­ed by propo­si­tion, and which have proven ver­i­ta­bly tough to explain. Study­ing both mar­vels togeth­er could help unrav­el the rid­dle behind them.
“The very real­i­ty of high- fre­quence ret­ro­grade modes and their ori­gin is a true enig­ma and may allude to instiga­tive drugs at play,“says physi­cist Shra­van Hana­soge of New York Uni­ver­si­ty, Abu Dhabi.
 
“It has the implic­it to exfo­li­ate per­cep­tion on the else unob­serv­able inside of the Sun.”
