Confirmation of a Non‐Transiting Planet in the Habitable Zone of the Nearby M Dwarf L 98‐59
Astronomische Nachrichten, EarlyView.ABSTRACT Only 40 exoplanetary systems with five or more planets are currently known. These systems are crucial for our understanding of planet formation and planet‐planet interaction. The M dwarf L 98‐59 has previously been found to show evidence of five planets, three of which are transiting.

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.

Photometric Modeling and Correction of the JiLin-1 Lunar Observations Using the Hapke Model
IEEE Journal of Selected Topics in Applied Earth Observations and Remote SensingThe PMS2 spectral imager onboard JiLin-1 (JL-1) satellite conducted extensive lunar observations, capturing images of the Moon across multiple spectral bands ranging from 415 to 1012 nm, spanning a wide range of lunar phases over an extended period ...

Steps toward a classifier for the Virtual Observatory. I. Classifying the SDSS photometric archive
, 2007 Modern photometric multiband digital surveys produce large amounts of data that, in order to be effectively exploited, need automatic tools capable to extract from photometric data an objective classification. We present here a new method for classifying

Biotechnology and Applied Biochemistry, EarlyView.ABSTRACT Neurodegenerative diseases, including Alzheimer's disease (AD) and Parkinson's disease (PD), are characterized by the pathological aggregation of specific proteins such as amyloid beta (Aβ) and α‐synuclein, respectively. Early detection of these protein aggregates in biological fluids could facilitate timely diagnosis and therapeutic ...

Aggregating Spatial and Photometric Context for Photometric Stereo
Photometric stereo, a computer vision technique for estimating the 3D shape of objects through images captured under varying illumination conditions, has been a topic of research for nearly four decades. In its general formulation, photometric stereo is an ill-posed problem and requires robust prior knowledge of material reflectance properties, light ...
