Journal of Phycology, EarlyView.Abstract Picocystis salinarum is an early‐diverging chlorophyte and the sole described member of the Picocystophyceae, frequently dominating hypersaline and alkaline lakes despite extreme physicochemical constraints. To elucidate the genomic foundations of its ecological success, we generated a fully annotated, chromosome‐scale nuclear genome assembly ...

Polarization measurements of some T Tauri stars [PDF]
Symposium - International Astronomical Union, 1987 T Tauri stars show linear polarization typically between 1–3%. A two band linear polarization survey of some T Tauri star was reported earlier by Bastien (1982). Most of the stars show pronounced time variability in polarization and position angle (Bastien, 1980; 1982).

The Astrophysical JournalMagnetospheric accretion is a key process that shapes the inner disks of T Tauri stars, controlling mass and angular momentum evolution. It produces strong ultraviolet and optical emission that irradiates the planet-forming environment.

James Lyman Merrick's Aborted “Mission to the Mohammedans of Persia”
The Muslim World, EarlyView.Abstract James Lyman Merrick (1803‐1866) served as a missionary of the American Board of Commissioners for Foreign Missions (ABCFM) in Persia between 1835 and 1845. He was America's first missionary to the Muslim world. Based on his field research on the Persians’ religious beliefs, he correctly predicted that the conversion of Persia's Muslims into ...

The Astrophysical JournalAn accurate estimation of the continuum excess emission from accretion spots and inner circumstellar disk regions is crucial for a proper derivation of fundamental stellar parameters in accreting systems.

The Astrophysical Journal, 2022 Accurate disk mass measurements are necessary to constrain disk evolution and the timescale of planet formation, but such measurements are difficult to make and are very dependent on assumptions. Here, we look at the assumption that the disk is optically

Environmental Microbiology Reports, Volume 18, Issue 5, October 2026.Analysing thousands of data points across 46 marine and freshwater strains, this study underscores that osmomixotrophy is a common, rather than exceptional, metabolic strategy in phytoplankton. These findings challenge the autotrophic paradigm, demonstrating that organic matter acquisition is a default state with significant implications for our ...

The Astronomical Journal, 1993 We present an atlas of 96 low dispersion spectra of T Tauri stars, both classical and weak-lined. The flux-calibrated spectra extend from Hβ to well blueward of the Balmer jump. Observed equivalent widths and rough blue veilings are presented. We model stars with excess emission as a combination of a weak-lined T Tauri star of a similar spectral type ...
