Stellar Populations of the Galactic Disk: Metallicity Distribution and Kinematics

open access: yesOpen Astronomy, 2003
Metallicities and distances have been determined from Vilnius photometry for an in situ sample of nearly 650 stars in eight proper-motion fields at high Galactic latitudes.

Single Stellar Populations [PDF]

open access: yesSymposium - International Astronomical Union, 1999
To determine metallicity and age distributions of globular clusters (GCs) in distant galaxies–now accessible, e.g. to Keck spectroscopy–it is important to have reliable calibrations of the color-metallicity, color-age, and index-metallicity relations.

Defining Roles in Pediatric Palliative Care: Perspectives From Oncology and Palliative Care Teams

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Early integration of pediatric palliative care (PPC) is associated with improved symptom management, quality of life, and healthcare utilization for children with cancer. Despite this, variation persists in how PPC is understood, operationalized, and integrated within pediatric oncology programs. In particular, ambiguity surrounding

Stellar Populations in the Extreme Outer Halo of the Spiral Galaxy M96

open access: yesThe Astrophysical Journal
We use deep Hubble Space Telescope imaging to study stellar populations in the outer halo of the spiral galaxy M96, located in the dynamically active Leo I galaxy group.

Hot Stars in Stellar Populations of Galaxies

open access: yesGalaxies
Star-forming galaxies are hosts of dominant populations of recently formed, hot, massive stars, which give rise to conspicuous stellar spectral features and provide the ionizing fluxes. Strong outflows of these stars shape their properties.

Stellar population analysis on local infrared-selected galaxies

open access: yes, 2009
To study the stellar population of local infrared galaxies, which contain star-forming galaxies, composite galaxies, LINERs, and Seyfert 2s. We also want to find whether infrared luminosity and spectral class have any effects on their stellar populations.

Efficacy and Safety Analysis of Roxarestat in Regulating Renal Anemia in Patients on Maintenance Hemodialysis

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Objective To compare the efficacy and safety of roxarestat versus recombinant human erythropoietin (rhEPO) in the management of renal anemia in patients undergoing maintenance hemodialysis. Methods This was a prospective, open‐label, randomized controlled trial.

Do Red Galaxies Form More Stars than Blue Galaxies?

open access: yesThe Astrophysical Journal
A new model is proposed in which typical galaxies form most of their stellar mass in a phase with an intrinsically red stellar population. In the standard picture, galaxies with intrinsically red stellar populations are believed to have old stellar ...
