The Astronomical Journal, 2023 Young eclipsing binaries (EBs) are powerful probes of early stellar evolution. Current models are unable to simultaneously reproduce the measured and derived properties that are accessible for EB systems (e.g., mass, radius, temperature, and luminosity).

Dynamical Stellar Masses of Pre-main-sequence Stars in Lupus and Taurus Obtained with ALMA Surveys in Comparison with Stellar Evolutionary Models [PDF]
, 2020 We analyzed archival molecular line data of pre-main-sequence (PMS) stars in the Lupus and Taurus star-forming regions obtained with ALMA surveys with an integration time of a few minutes per source. We stacked the data of 13CO and C18O (J = 2–1 and 3–2)

INTRINSIC COLORS, TEMPERATURES, AND BOLOMETRIC CORRECTIONS OF PRE-MAIN-SEQUENCE STARS [PDF]
, 2013 We present an analysis of the intrinsic colors and temperatures of 5–30 Myr old pre-main-sequence (pre-MS) stars using the F0- through M9-type members of nearby, negligibly reddened groups: the η Cha cluster, the TW Hydra Association, the β Pic Moving ...

New evolutionary models for pre-main sequence and main sequence low-mass stars down to the hydrogen-burning limit [PDF]
, 2015 We present new models for low-mass stars down to the hydrogen-burning limit that consistently couple atmosphere and interior structures, thereby superseding the widely used BCAH98 models.

Masses and Implications for Ages of Low-mass Pre-main-sequence Stars in Taurus and Ophiuchus [PDF]
Astrophysical Journal, 2019 The accuracy of masses of pre-main-sequence stars derived from their locations on the Hertzsprung–Russell diagram (HRD) can be tested by comparison with accurate and precise masses determined independently.

Pre-main sequence stars in LH 91
Astronomy & Astrophysics, 2022 Aims. We study the accretion properties of pre-main sequence (PMS) low-mass stars in the LH 91 association within the Large Magellanic Clouds. Methods. Using optical multiband photometry obtained with the Hubble Space Telescope, we identify 75 candidates showing Hα excess emission above the 3σ level with equivalent width EWHα ⩾ 10 Å.

PRE-MAIN SEQUENCE EVOLUTIONS OF SOLAR ABUNDANCE LOW MASS STARS [PDF]
Journal of Astronomy and Space Sciences, 2007 We present the Pre-Main Sequence (PMS) evolutionary tracks of stars with 0.065~5.0M_⨀. The models were evolved from the PMS stellar birthline to the onset of hydrogen burning in the core.

Abundance anomalies in pre-main-sequence stars: Stellar evolution models with mass loss [PDF]
, 2010 The effects of atomic diffusion on internal and surface abundances of A and F pre-main-sequence stars with mass loss are studied in order to determine at what age the effects materialize, as well as to further understand the processes at play in HAeBe ...

Long-term optical photometric monitoring of the FUor star V900 Mon [PDF]
Serbian Astronomical Journal, 2021 We present results from photometric monitoring of V900 Mon, one of the newly discovered and still under-studied object from the FU Orionis type. The FUor phenomenon is very rarely observed, but it is essential for stellar evolution.
