Eclipsing binary and white dwarf features associated with K2 target EPIC251248385 [PDF]

open access: yes, 2019
White dwarfs, remnants of Sun-like stars which have completed their evolution, are one of the most common types of stars in space. Despite this, very few white dwarfs have been observed in transiting or eclipsing systems, and only two planetary systems ...

A search for transits of GJ 581\lowercase{e} and characterization of the host star variability using MOST space telescope photometry [PDF]

open access: yes, 2012
The GJ 581 system has been amply studied since its discovery in 2005: the number of known planets in the system has increased and their orbital parameters are among the most precisely determined for radial velocity detected exoplanets.

Up-down biphasic volume response of human red blood cells to PIEZO1 activation during capillary transits.

open access: yesPLoS Computational Biology, 2021
In this paper we apply a novel JAVA version of a model on the homeostasis of human red blood cells (RBCs) to investigate the changes RBCs experience during single capillary transits.

Characterizing the Near-infrared Spectra of Flares from TRAPPIST-1 during JWST Transit Spectroscopy Observations

open access: yesThe Astrophysical Journal, 2023
We present the first analysis of JWST near-infrared spectroscopy of stellar flares from TRAPPIST-1 during transits of rocky exoplanets. Four flares were observed from 0.6–2.8 μ m with the Near Infrared Imager and Slitless Spectrograph and 0.6–3.5 μ m ...

Spatial solitary-wave optical memory [PDF]

open access: yes, 1990
We consider some features of spatial solitary-wave switching in a unidirectional ring cavity that is partially filled with a fast and saturably self-focusing nonlinear medium. Large (part-beam switched) solitary arrays are considered.

Efficient analysis in planet transit surveys [PDF]

open access: yes, 2005
With the growing number of projects dedicated to the search for extrasolar planets via transits, there is a need to develop fast, automatic, robust methods with a statistical background in order to efficiently do the analysis.

Transit Lightcurve Signatures of Artificial Objects [PDF]

open access: yes, 2005
The forthcoming space missions, able to detect Earth-like planets by the transit method, will a fortiori also be able to detect the transit of artificial planet-size objects.

TESS Spots a Super-puff: The Remarkably Low Density of TOI-1420b

open access: yesThe Astronomical Journal, 2023
We present the discovery of TOI-1420b, an exceptionally low-density ( ρ = 0.08 ± 0.02 g cm ^−3 ) transiting planet in a P = 6.96 days orbit around a late G-dwarf star.

Time resolved spectroscopy of dust and gas from extrasolar planetesimals orbiting WD 1145+017

open access: yes, 2018
Multiple long and variable transits caused by dust from possibly disintegrating asteroids were detected in light curves of WD 1145+017. We present time-resolved spectroscopic observations of this target with QUCAM CCDs mounted in the Intermediate ...

Planet Hunters. VIII. Characterization of 41 Long-Period Exoplanet Candidates from Kepler Archival Data [PDF]

open access: yes, 2015
The census of exoplanets is incomplete for orbital distances larger than 1 AU. Here, we present 41 long-period planet candidates in 38 systems identified by Planet Hunters based on Kepler archival data (Q0-Q17).
