On the Habitability of Teegarden’s Star Planets [PDF]
The Astrophysical Journal Letters, 2019 Abstract We study the habitability of the two Earth-mass planets, recently detected by the CARMENES collaboration, around the ultra-cool nearby M-dwarf Teegarden’s Star. With orbital periods of 4.9 and 11.4 days, both planets are likely to be within the habitable zone and

THE IMPACT OF STELLAR ROTATION ON THE DETECTABILITY OF HABITABLE PLANETS AROUND M DWARFS [PDF]
, 2016 Stellar activity and rotation frustrate the detection of exoplanets through the radial velocity technique. This effect is particularly of concern for M dwarfs, which can remain magnetically active for billions of years.

Ocean Dynamics and the Inner Edge of the Habitable Zone for Tidally Locked Terrestrial Planets [PDF]
Astrophysical Journal, 2019 Recent studies have shown that ocean dynamics can have a significant warming effect on the permanent night sides of 1:1 tidally locked terrestrial exoplanets with Earth-like atmospheres and oceans in the middle of the habitable zone.

On the radius of habitable planets [PDF]
Astronomy & Astrophysics, 2013 The conditions that a planet must fulfill to be habitable are not precisely known. However, it is comparatively easier to define conditions under which a planet is very likely not habitable. Finding such conditions is important as it can help select, in an ensemble of potentially observable planets, which ones should be observed in greater detail for ...

Biosignatures Search in Habitable Planets [PDF]
Galaxies, 2019 The search for life has had a new enthusiastic restart in the last two decades thanks to the large number of new worlds discovered. The about 4100 exoplanets found so far, show a large diversity of planets, from hot giants to rocky planets orbiting small and cold stars.

Three‐dimensional swimming behavior and activity of a mesopelagic fish
Limnology and Oceanography, Volume 67, Issue 12, Page 2677-2690, December 2022., 2022 Abstract Knowledge of the three‐dimensional behavior and activity patterns of mesopelagic fishes is crucial for understanding their role in ecological and biogeochemical processes in the ocean. We here show that the use of submerged stationary echosounders enables detailed analysis of three‐dimensional swimming behavior of small mesopelagic fishes in ...

A More Comprehensive Habitable Zone for Finding Life on Other Planets [PDF]
Géosciences, 2018 The habitable zone (HZ) is the circular region around a star(s) where standing bodies of water could exist on the surface of a rocky planet. Space missions employ the HZ to select promising targets for follow-up habitability assessment.

Accounting for Multiplicity in Calculating Eta Earth [PDF]
, 2019 Using the updated exoplanet population parameters of our previous study, which includes the planetary radius updates from Gaia DR2 and an inferred multiplicity distribution, we provide a revised $\eta_{\oplus}$ calculation.

Limnology and Oceanography: Methods, Volume 20, Issue 12, Page 789-810, December 2022., 2022 Abstract Mid‐trophic level (MTL) organisms play a key role in the sub‐Antarctic ecosystem food web, linking primary producers and tertiary consumers transferring energy across trophic levels. In this region, the relative abundance of MTLs has been monitored using single‐frequency acoustic data collected opportunistically in a time series of trawl ...

Geophysical and Atmospheric Evolution of Habitable Planets [PDF]
Astrobiology, 2010 The evolution of Earth-like habitable planets is a complex process that depends on the geodynamical and geophysical environments. In particular, it is necessary that plate tectonics remain active over billions of years. These geophysically active environments are strongly coupled to a planet's host star parameters, such as mass, luminosity and activity,
