Commissioning an Inexpensive Off‐The‐Shelf Spectrograph for Radial‐Velocity Studies

open access: yesAstronomische 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.

Searching for Rotational X‐Ray Modulation on TIC 277539431

open access: yesAstronomische Nachrichten, EarlyView.
ABSTRACT TIC 277539431, a fast rotating M7 dwarf, was detected to host the highest latitude flare to date at 81°$$ {81}^{{}^{\circ}} $$. Magnetic activity like stellar flares occurring at high latitude indicate occurrence of coronal loops at these latitudes on fully‐convective M dwarfs. In contrast, sunspots usually occur below 30°$$ {30}^{{}^{\circ}} $

Atypical Visually Guided Precision Grip Control in Middle‐Aged and Older Autistic Adults

open access: yesAutism Research, EarlyView.
ABSTRACT Sensorimotor impairments are well documented in autism spectrum disorder (ASD). However, little is known about how these difficulties present in middle‐aged and older autistic adults or how they relate to demographic factors and autistic traits.
