A Blind Search for Transit Depth Variability with TESS

The Astronomical Journal, 2023
The phenomenon of transit depth variability offers a pathway through which processes such as exoplanet atmospheric activity and orbital dynamics can be studied.

Contributions of structural variations to the asymptotic mixed‐mode coupling Factor in red giant stars

Astronomische Nachrichten, Volume 343, Issue 9-10, November-December 2022., 2022
Abstract The advent of ultra‐precise photometry space missions enables the possibility of investigating stellar interiors with mixed modes. The structural variations induced by the discontinuity of the chemical composition left behind during the first dredge–up is an important feature in the stellar mid‐layers located between the hydrogen‐burning shell

Multiwavelength Transit Observations of the Candidate Disintegrating Planetesimals Orbiting WD 1145+017 [PDF]

, 2015
We present multiwavelength, multi-telescope, ground-based follow-up photometry of the white dwarf WD 1145+017, that has recently been suggested to be orbited by up to six or more, short-period, low-mass, disintegrating planetesimals.

TOI-4600 b and c: Two Long-period Giant Planets Orbiting an Early K Dwarf

The Astrophysical Journal Letters, 2023
We report the discovery and validation of two long-period giant exoplanets orbiting the early K dwarf TOI-4600 ( V = 12.6, T = 11.9), first detected using observations from the Transiting Exoplanet Survey Satellite (TESS) by the TESS Single Transit ...

A comparison of methods to assess the resistance of reinforcing steel against chloride‐induced corrosion in concrete: Particular consideration of 12% chromium steel

Materials and Corrosion, EarlyView., 2021
Several methods to measure the critical chloride content Ccrit of steel in concrete are compared on the basis of 12% chromium steel and carbon steel. The resulting Ccrit depends on the method used. The reasons for this and the corresponding influencing parameters are discussed in this article.

Toward Detection of Exoplanetary Rings via Transit Photometry: Methodology and a Possible Candidate [PDF]

, 2017
The detection of a planetary ring of exoplanets remains one of the most attractive, but challenging, goals in the field of exoplanetary science. We present a methodology that implements a systematic search for exoplanetary rings via transit photometry of

Exploiting the molecular diversity of the synapse to investigate neuronal communication: A guide through the current toolkit

European Journal of Neuroscience, Volume 56, Issue 12, Page 6141-6161, December 2022., 2022
Chemical synapses are tiny and overcrowded environments enriched with thousands of protein species. Many efforts have been devoted to developing sensors and actuators able to evaluate and control synaptic communication. Most of these recent tools are based on the engineering of one or more specific synaptic proteins used to target active moieties to ...

Exoplanet transit spectro-photometry with SOFIA [PDF]

Proceedings of the International Astronomical Union, 2010
AbstractWe present the prospects of observing extrasolar planets with the Stratospheric Observatory for Infrared Astronomy (SOFIA). Our analysis shows that optical and near-infrared photometric and spectrophotometric follow-up observations during planetary transits and\break eclipses will be feasible with SOFIA's instrumentation, especially with the ...

Unveiling an exoplanetary Neptunian atmosphere through multiband transit photometry [PDF]

Proceedings of the International Astronomical Union, 2013
AbstractThe “effective” radius of a planet is a function of wavelength due to scattering and/or absorption processes, and we can exploit simultaneous multiband transit photometry to probe the atmospheric scale height and composition. We present new photometric data of the recently discovered “hot Uranus” GJ3470b, gathered with the LBC camera at LBT ...

TOI-5205b: A Short-period Jovian Planet Transiting a Mid-M Dwarf

The Astronomical Journal, 2023
We present the discovery of TOI-5205b, a transiting Jovian planet orbiting a solar metallicity M4V star, which was discovered using Transiting Exoplanet Survey Satellite photometry and then confirmed using a combination of precise radial velocities ...
