The spectroscopic study of M8.5-M9.5 stars and brown dwarfs
EPJ Web of Conferences, 2013 We present high-resolution spectra analysis of the three late-M dwarfs LP944-20, SIPS J2045-6332 and DENIS-P J0021.0-4244. The stellar spectra were observed with Very Large Telescope/Ultraviolet–Visual Echelle Spectrograph (VLT/UVES) in optical and near ...

LATIS: The Stellar Mass–Metallicity Relation of Star-forming Galaxies at z ∼ 2.5
The Astrophysical Journal, 2023 We present the stellar mass–stellar metallicity relation for 3491 star-forming galaxies at 2 ≲ z ≲ 3 using rest-frame far-ultraviolet spectra from the Ly α Tomography IMACS Survey (LATIS).

The Astrophysical JournalData-driven models for stellar spectra that depend on stellar labels suffer from label systematics which decrease model performance: the stellar labels gap.

Publications of the Astronomical Society of the Pacific, 1944 Phi Persei. This star has a well-known helium-shell spectrum, with He i 3965 sharp, while those lines which have nonmetastable lower levels are usually broad and shallow. The H lines show absorption cores between broad emission wings. Several spectrograms, obtained on October 22, 1951, with the coude spectrograph of the Mount Wilson 100-inch telescope ...

On the information content of stellar spectra [PDF]
Proceedings of the International Astronomical Union, 2013 AbstractWith the increasing quality of asteroseismic observations it is important to minimize the random and systematic errors in mode parameter estimates. To this end it is important to understand how the oscillations relate to the directly observed quantities, such as intensities and spectra, and to derived quantities, such as Doppler velocity.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background PIK3CA‐related overgrowth spectrum (PROS) includes several rare overgrowth disorders resulting from somatic gain‐of‐function mutations in PIK3CA. Despite treatment advances, including the recent approval of alpelisib for PROS in the United States, literature detailing the patient experience with PROS is limited.
