PPV Chapter - The Formation of Brown Dwarfs [PDF]
arXiv, 2006 We review five mechanisms for forming brown dwarfs: (i) turbulent fragmentation of molecular clouds, producing very low-mass prestellar cores by shock compression; (ii) collapse and fragmentation of more massive prestellar cores; (iii) disc fragmentation; (iv) premature ejection of protostellar embryos from their natal cores; and (v) photo-erosion of ...

Fecundity, Fertility and The Formation of Human Capital
The Economic Journal, EarlyView., 2018 Exploiting a genealogy of English individuals living in the 16th to the 19th centuries, this study shows that lower parental reproductive capacity positively affected the socio‐economic achievements of offspring. Using the time interval between the date of marriage and the first birth as a measure of reproductive capacity, we find that parental ...

Brown Dwarf Candidates in the JADES and CEERS Extragalactic Surveys
The Astrophysical JournalBy combining the James Webb Space Telescope (JWST)/NIRCam JADES and CEERS extragalactic data sets, we have uncovered a sample of 21 T and Y brown dwarf candidates at best-fit distances between 0.1 and 4.2 kpc. These sources were selected by targeting the

Integrative Zoology, EarlyView.Microorganism‐released metabolites, proteins, or toxins modulate plant‐based targets to regulate physiological processes such as phytohormone and nutrition balance and stress resistance. Microbes that affect plant physiological processes regulate the visual, olfactory, and gustatory cues associated with plants to attract or repel insect herbivores and ...
