Cardiac output and stroke volume variation measured by the pulse wave transit time method: a comparison with an arterial pressure-based cardiac output system [PDF]

open access: yesJournal of Clinical Monitoring and Computing, 2018
Hemodynamic monitoring is mandatory for perioperative management of cardiac surgery. Recently, the estimated continuous cardiac output (esCCO) system, which can monitor cardiac output (CO) non-invasively based on pulse wave transit time, has been developed.

The TESS-Keck Survey. XV. Precise Properties of 108 TESS Planets and Their Host Stars

open access: yesThe Astronomical Journal, 2023
We present the stellar and planetary properties for 85 TESS Objects of Interest (TOIs) hosting 108 planet candidates that compose the TESS-Keck Survey (TKS) sample.

Metrics for Optimizing Searches for Tidally Decaying Exoplanets

open access: yesThe Astronomical Journal, 2023
Tidal interactions between short-period exoplanets and their host stars drive orbital decay and have likely led to engulfment of planets by their stars.

Dynamics and Origins of the Near-resonant Kepler Planets

open access: yesThe Astrophysical Journal, 2023
Short-period super-Earths and mini-Neptunes encircle more than ∼50% of Sun-like stars and are relatively amenable to direct observational characterization.

Lack of Transit Timing Variations of OGLE-TR-111b: A re-analysis with six new epochs [PDF]

open access: yes, 2010
We present six new transits of the exoplanet OGLE-TR-111b observed with the Magellan Telescopes in Chile between April 2008 and March 2009. We combine these new transits with five previously published transit epochs for this planet between 2005 and 2006 ...

TOI-199 b: A Well-characterized 100 day Transiting Warm Giant Planet with TTVs Seen from Antarctica

open access: yesThe Astronomical Journal, 2023
We present the spectroscopic confirmation and precise mass measurement of the warm giant planet TOI-199 b. This planet was first identified in TESS photometry and confirmed using ground-based photometry from ASTEP in Antarctica including a full 6.5 hr ...

Practical suggestions on detecting exomoons in exoplanet transit light curves

open access: yes, 2010
The number of known transiting exoplanets is rapidly increasing, which has recently inspired significant interest as to whether they can host a detectable moon. Although there has been no such example where the presence of a satellite was proven, several

How to determine an exomoon's sense of orbital motion [PDF]

open access: yes, 2014
We present two methods to determine an exomoon's sense of orbital motion (SOM), one with respect to the planet's circumstellar orbit and one with respect to the planetary rotation. Our simulations show that the required measurements will be possible with

Probing the Possible Causes of the Transit Timing Variation for TrES-2b in the TESS Era

open access: yesThe Astronomical Journal
Nowadays, transit timing variations (TTVs) are proving to be a very valuable tool in exoplanetary science to detect exoplanets by observing variations in transit times. To study the TTV of the hot Jupiter TrES-2b, we have combined 64 high-quality transit

Long-term Variations in the Orbital Period of Hot Jupiters from Transit-timing Analysis Using TESS Survey Data

open access: yesThe Astrophysical Journal Supplement Series
Many hot Jupiters may experience orbital decays, which are manifested as long-term transit-timing variations. We have analyzed 7068 transits from the Transiting Exoplanet Survey Satellite (TESS) for a sample of 326 hot Jupiters.
