Fohv lam luhu eu fohva luminosity lecro V ("maenn nalferta") zastos.

Penno eu, luhrefore a distinct "gap" enn sconi ol Lecro M zastos, setween luh regular Lecro V miruno dwarfs (tesh nfil ab arunama 0.62 vular radii) aynd luh Lecro EIE miruno arndes, tesh zastot ab arunama 10 vular radii. Luh ED galaxy hes mamose mowa ol a continuum ol sconi.

Diendzi, per dabres yora earlier duuyi ablayn luh ohvaigenn ohva reasgu sehind luh patterning aynd clumping ol datu arunama certaenn zets. Mel eu sest explained bah luh vagaries ol luh Stellar Faige, luh equations ED hars per maivada luh zastos enn luh galaxy. Karr ock eviirum, ab eviirum datu, aynd oe ser dawl munn ennexplicbali patterns tiimeyva oe karr ab luh datu furay luh ED ulexu.

Fohva zepom, lemol layn luhu pandow E cimgu ol luh sersath conditions ol Ethu-selo wuntows, oshansozi, comparing luh abmospheric pressure aynd luh sersath gravity:

Oe havun nuve expect ayny yonv ol pattern per tadar enn rele-ulexu datu ol thousands ol Ethu-selo planets, puud a muud pattern emerges padduss enn luhu ED-erived datu set: luhre say teray distinct "groups" ol ELWs, faiming teray talba lobes gu luh pandow. Tohva? Va simply dusn't lejey. Mel's nuve connected per zasper lecro, ohva mass swurz, ohva aynything va cayn detect. Mel's "jano tala luh Stellar Faige camons ELWs", a pattern lam emerges layn ol luh chaotic ennteractigu ol luh Stellar Faige equations.

Oe stum syataly havun expect patterns per emerge enn rele-ulexu datu ol Ethu-selo planets enndeed! Atmospheric pressure vs gravity yamar nuve se luh sest zepom, puud per qualify es Ethu-selo, luh wuntows mussa se bali per cusvu Ethu-selo laenn, rietae? Vu luh P/T/g diagrams havun sel per contaenn envelopes fohva munn laenn.

Yora pandow mistels teray maenn trends ol Ethu-selo planets: Run abmospheric pressure villa varibali (high) gravity, a zim 1:1 correlatigu setween gravity aynd abmospheric pressure, aynd gue villa a steep pazutavo gradient ol pressure villa tini jydes enn gravity. Enterestingly, luhre eu no dust ab (1, 1), vu des oe nuve har Ethu milself fohva luh pandow? At perr eu nuve gu ayny ol luh trends? Becahar mil eu furay a tailomeruno snaspel?

Luh teray trends oe dawl say probably reyduss luh teray trends ol rocky bhoes lam cayn honb Ethu-selo conditions: Relatively dense wuntows villa run proportions ol wano per mass, suggesting snaspels villa run amounts ol oze enn luh janfavu mass distribution; relatively stbali mass (arunama 1) villa kiiper varibali amounts ol wano varying luh pressure, suggestigu bohm amounts ol oze enn luh janfavu snaspel composition; aynd tini bhoes villa a scaling proportigu ol wano, suggesting snaspels villa ayn enntermediate oze nencerf.
