Detection of Semidetached Eclipsing Binaries from TESS
The Astronomical JournalSemidetached binaries, distinguished by their mass transfer phase, play a crucial role in elucidating the physics of mass transfer within interacting binary systems.

Precision Timing of Eclipsing Binaries from TESS Full Frame Images: Method and Performance
The Astrophysical JournalSeveral hundreds of thousands of eclipsing binaries (EBs) are expected to be detected in the Transiting Exoplanet Survey Satellite (TESS) full frame images (FFIs).

TIC 290061484: A Triply Eclipsing Triple System with the Shortest Known Outer Period of 24.5 Days
The Astrophysical JournalWe have discovered a triply eclipsing triple-star system, TIC 290061484, with the shortest known outer period, P _out , of only 24.5 days. This “eclipses” the previous record set by λ Tauri at 33.02 days, which held for 68 yr.

Commissioning an Inexpensive Off‐The‐Shelf Spectrograph for Radial‐Velocity Studies
Astronomische Nachrichten, EarlyView.ABSTRACT We present a way to set up an inexpensive out of the shelf spectrograph at a local observatory. Stability and resolution of the spectrograph are high enough for radial velocity determination of binary stars or determination of stellar characteristics. Even some exoplanets might be detectable via the radial velocity method.

‘Where are the adults?’: Troubling child‐activism and children's political participation
British Educational Research Journal, EarlyView.Abstract Children's political participation is a well‐established theme in childhood studies. In this article we offer an original account of child activism that takes into account the entangled and emergent aspect of children as activists. We begin with a historical and a conceptual review, noting the importance of mid‐20th century developments such ...

Cytoskeleton, EarlyView.ABSTRACT Lateral root (LR) organogenesis is regulated by cellular flux of auxin within pericycle cells, which depends on the membrane distribution and polar localization of auxin carrier proteins. The correct distribution of auxin carrier proteins relies on the intracellular trafficking of these proteins aided by filamentous actin as a track.

Cytoskeleton, EarlyView.ABSTRACT Pollen is a male gametophyte of angiosperms. Following meiosis, the microspore undergoes an asymmetric division called pollen mitosis I (PMI), which produces two cells of different sizes: a large vegetative cell and a small generative cell. Polarized nuclear migration and positioning during PMI are important for successful pollen development ...

Radial velocity and light curves analysis of the eclipsing binary NN Vir
Odessa Astronomical Publications, 2017 The eclipsing binary NN Vir is a short period system showing an EW-type light curve. Photometric Observations of NN Vir were done by Gomez-Ferrellad & Garcia-Melendo (1997) at Esteve Duran Observatory.
