Stellar Flare Study of nearby Young Moving Group Members with TESS Data

The Astrophysical Journal
We analyze TESS data to explore stellar flares and rotational characteristics in members of nearby young moving groups (NYMGs). Our study focuses on 417 members of NYMGs aged 10–150 Myr.

STELLAR WIND IN THE ISM

Odessa Astronomical Publications, 2017
After a brief review of the modern understanding of stellar wind's action on the ISM we consider two aspects of its "global" collective effect from observational viewpoint.

PHANGS–JWST First Results: Multiwavelength View of Feedback-driven Bubbles (the Phantom Voids) across NGC 628

The Astrophysical Journal Letters, 2023
We present a high-resolution view of bubbles within the Phantom Galaxy (NGC 628), a nearby (∼10 Mpc), star-forming (∼2 M _⊙ yr ^−1 ), face-on ( i ∼ 9°) grand-design spiral galaxy.

The Origin of Massive O-type Field Stars. Part II: Field O stars as runaways [PDF]

, 2005
In two papers we try to confirm that all Galactic high-mass stars are formed in a cluster environment, by excluding that O-type stars found in the Galactic field actually formed there. In de Wit et al.

Mass Outflows Associated with Young Stellar Objects [PDF]

Symposium - International Astronomical Union, 1987
The fundamental properties of optical and molecular outflows associated with young stellar objects are reviewed. Particular emphasis is placed on a discussion of new results concerning outflow energetics, collimating structures and the relationship between outflow properties and the magnetic field geometry characterizing their host molecular clouds ...

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...

Kinematic Age of the β-Pictoris Moving Group

The Astrophysical Journal
Accurate age estimation of nearby young moving groups (NYMGs) is important as they serve as crucial testbeds in various fields of astrophysics, including the formation and evolution of stars and planets, as well as loose stellar associations.

A Census of the Stellar Populations in the Sco-Cen Complex

The Astronomical Journal, 2021
I have used high-precision photometry and astrometry from the early installment of the third data release of Gaia (EDR3) to perform a survey for members of the stellar populations within the Sco-Cen complex, which consist of Upper Sco, UCL/LCC, the V1062

Clinical Insights Into Hypercalcemia of Malignancy in Childhood

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Hypercalcemia of malignancy (HCM) is a rare but life‐threatening metabolic emergency in children that occurs in less than 1% of pediatric cancer cases, with a reported incidence ranging from 0.4% to 1.0% across different studies. While it is observed in 10%–20% of adult malignancies, pediatric HCM remains relatively uncommon.

Kinematic Ages of the Tucana–Horologium, Columba, and Carina Associations

The Astrophysical Journal
The traceback method allows the computation of the kinematic age of nearby young associations from astrometric and kinematic data alone, circumventing the need for stellar evolution models.
