Variability of Young Massive Stars in the Galactic Super Star Cluster Westerlund 1

open access: yes, 2007
This paper presents the first optical variability study of the Westerlund 1 super star cluster in search of massive eclipsing binary systems. A total of 129 new variable stars have been identified, including the discovery of 4 eclipsing binaries that are

Variability of Known Exoplanet Host Stars Observed by TESS

open access: yesThe Astronomical Journal, 2023
Both direct and indirect methods of exoplanet detection rely upon detailed knowledge of the potential host stars. Such stellar characterization allows for accurate extraction of planetary properties, as well as contributing to our overall understanding ...

Classification of Periodic Variable Stars from TESS

open access: yesThe Astrophysical Journal Supplement Series
The number of known periodic variable stars has increased rapidly in recent years. As an all-sky transit survey, the Transiting Exoplanet Survey Satellite (TESS) plays an important role in detecting low-amplitude variable stars.

Observations of red-giant variable stars by Aboriginal Australians

open access: yes, 2017
Aboriginal Australians carefully observe the properties and positions of stars, including both overt and subtle changes in their brightness, for subsistence and social application. These observations are encoded in oral tradition.

Real‐World Pediatric Blinatumomab Administration: Access to Outpatient Care Delivery and Impact of a Hospital‐Dispensed Model

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Blinatumomab has been shown to be highly effective for patients with pediatric B‐ALL and has recently become standard of care therapy. Due to its past use in the clinical trial setting, there is limited information available about real‐world administration.

Period–Luminosity Relations for Double-mode δ Sct Stars

open access: yesThe Astrophysical Journal
Previous studies of the period–luminosity relations (PLRs) of Delta Scuti ( δ Sct) stars have focused on those with a single pulsation mode. However, for δ Sct stars with many different pulsation modes, classifying a single mode is difficult.

Discovery of magnetic fields in three He variable Bp stars with He and Si spots [PDF]

open access: yes, 2006
It is essential for the understanding of stellar structure models of high mass stars to explain why constant stars, non-pulsating chemically peculiar hot Bp stars and pulsating stars co-exist in the slowly pulsating B stars and beta Cephei instability ...

Observations of Long Period Variable Stars [PDF]

open access: yesInternational Astronomical Union Colloquium, 1989
The study of long period variable stars has been transformed in recent years by two observational developments. Large samples of stars have been observed at infrared wavelengths, providing knowledge of the intrinsic properties of the star as well as of circumstellar dust shells, and these observations have been extended to the variables in well defined
