Sulforaphane and ophthalmic diseases. [PDF]
Food Sci NutrSulforaphane (SFN) is an organosulfur compound categorized as an isothiocyanate (ITC), primarily extracted from cruciferous vegetables like broccoli and cabbage. This review comprehensively outlines recent research on SFN, elucidates its mechanisms of action, and discusses potential therapeutic benefits for eye disorders such as age‐related macular ...

Radiation Transfer of Models of Massive Star Formation. III. The Evolutionary Sequence [PDF]
, 2014 We present radiation transfer (RT) simulations of evolutionary sequences of massive protostars forming from massive dense cores in environments of high surface densities. The protostellar evolution is calculated with a detailed multi-zone model, with the

Identification of A Collapsing Protostar [PDF]
Astrophysics and Space Science, 1994 The globular molecular cloud B335 contains a single, deeply embedded, far-infrared source. Our recent observations of H2CO and CS lines toward this source provide direct kinematic evidence for collapse. Both the intensity and detailed shape of the line profiles match those expected from inside-out collapse inside a radius of 0.036 pc.

Observed luminosity spread in young clusters and Fu Ori stars: a unified picture [PDF]
, 2012 The idea that non steady accretion during the embedded phase of protostar evolution can produce the observed luminosity spread in the Herzsprung-Russell diagram (HRD) of young clusters has recently been called into question.

Protostar Formation in the Early Universe [PDF]
Science, 2008 The nature of the first generation of stars in the universe remains largely unknown. Observations imply the existence of massive primordial stars early in the history of the universe, and the standard theory for the growth of cosmic structure predicts that structures grow hierarchically through gravitational instability.

On Solar Type Protostars [PDF]
International Astronomical Union Colloquium, 1980 The formation of a 1 M⊙ protostar in spherical symmetry has been followed in time dependent hydrodynamics with a detailed description of the equation of state and a careful treatment of radiative transport. The comparison of the dynamic evolution with observation is made in terms of the Hertzprung-Russell diagram.

Properties of the Youngest Protostars in Perseus, Serpens, and Ophiuchus [PDF]
, 2008 We present an unbiased census of deeply embedded protostars in Perseus, Serpens, and Ophiuchus, assembled by combining large-scale 1.1 mm Bolocam continuum and Spitzer Legacy surveys.
