SUBSTELLAR SÖZCÜĞÜ İNGILIZCE DİLİNDE NE ANLAMA GELİR?
Alt tabaka nesnesi
Bazen bir alt madde olarak da adlandırılan alt nesne, kütlesi en küçük kütleden daha küçük, yaklaşık 0.08 güneş kütlesi olan bir yıldızın hidrojen füzyonunu sürdürebildiği astronomik bir cisimdir. Bu tanım, kahverengi cüceleri, EF Eridani B'ye benzer eski yıldızları ve bunların oluşum mekanizmalarına ve birincil bir yıldızla ilişkili olup olmamalarına bakılmaksızın gezegen kütlesi nesnelerini de içerebilir. Bir alt nesnenin Güneş'e benzer bir bileşime sahip olduğunu ve en azından Jüpiter'in kütlesini varsayarsak, yarıçapı Jüpiter'inkiyle karşılaştırılabilir olacaktır. Bunun nedeni, hidrojen yakma limitinin hemen altındaki bu alt tabakalı nesnenin merkezinin yoğunluğu ≈ 103 g / cm3 olan oldukça dejeneratif olmakla birlikte, bu dejenerasyon, Jüpiter'in kütlesinde bir alt nesne olana kadar kütlenin azalması ile azalır merkezi yoğunluk 10 g / cm3'den az. Yoğunluk, yarıçapı yaklaşık olarak sabit tutarak, kütlenin azalmasını dengeler.
İngilizce sözlükte substellar sözcüğünün tanımı
Sözlükteki alt yıldızların tanımı, nükleer füzyon için yıldızların ihtiyaç duyduğu kütleye oranla daha küçük kütleli astronomik bir cisimdir.

An Introduction to Close Binary Stars
For the surface element at the substellar point, the irradiating star is seen directly
overhead at all times as a limb-darkened disc, and the total received flux density
is equal to that from a point source obeying the inverse-square law. As one ...
