The solar cycle

DH Hathaway - Living reviews in solar physics, 2015 - Springer
The solar cycle is reviewed. The 11-year cycle of solar activity is characterized by the rise
and fall in the numbers and surface area of sunspots. A number of other solar activity …

Solar irradiance variability and climate

SK Solanki, NA Krivova, JD Haigh - Annual Review of …, 2013 - annualreviews.org
The brightness of the Sun varies on all timescales on which it has been observed, and there
is increasing evidence that this has an influence on climate. The amplitudes of such …

[HTML][HTML] The detection and attribution of northern hemisphere land surface warming (1850–2018) in terms of human and natural factors: Challenges of inadequate …

W Soon, R Connolly, M Connolly, SI Akasofu… - Climate, 2023 - mdpi.com
A statistical analysis was applied to Northern Hemisphere land surface temperatures (1850–
2018) to try to identify the main drivers of the observed warming since the mid-19th century …

Recent variability of the solar spectral irradiance and its impact on climate modelling

I Ermolli, K Matthes, T Dudok de Wit… - Atmospheric …, 2013 - acp.copernicus.org
The lack of long and reliable time series of solar spectral irradiance (SSI) measurements
makes an accurate quantification of solar contributions to recent climate change difficult …

Evolution of the solar irradiance during the Holocene

LEA Vieira, SK Solanki, NA Krivova… - Astronomy & …, 2011 - aanda.org
Context. Long-term records of solar radiative output are vital for understanding solar
variability and past climate change. Measurements of solar irradiance are available for only …

Using the Sun to estimate Earth-like planets detection capabilities-II. Impact of plages

N Meunier, M Desort, AM Lagrange - Astronomy & Astrophysics, 2010 - aanda.org
Aims. Stellar activity produced by spots and plages affects the radial velocity (RV)
signatures. Because even low activity stars would produce such a signal, it is crucial to …

Exclusion of cosmic rays in protoplanetary disks: stellar and magnetic effects

LI Cleeves, FC Adams, EA Bergin - The Astrophysical Journal, 2013 - iopscience.iop.org
Cosmic rays (CRs) are thought to provide an important source of ionization in the outermost
and densest regions of protoplanetary disks; however, it is unknown to what degree they are …

Reconstruction of total and spectral solar irradiance from 1974 to 2013 based on KPVT, SoHO/MDI, and SDO/HMI observations

KL Yeo, NA Krivova, SK Solanki… - Astronomy & …, 2014 - aanda.org
Context. Total and spectral solar irradiance are key parameters in the assessment of solar
influence on changes in the Earth's climate. Aims. We present a reconstruction of daily solar …

Sunspot group tilt angles and the strength of the solar cycle

M Dasi-Espuig, SK Solanki, NA Krivova… - Astronomy & …, 2010 - aanda.org
Context. It is well known that the tilt angles of active regions increase with their latitude (Joy's
law). It has never been checked before, however, whether the average tilt angles change …

A revised collection of sunspot group numbers

JM Vaquero, L Svalgaard, VMS Carrasco, F Clette… - Solar Physics, 2016 - Springer
We describe a revised collection of the number of sunspot groups from 1610 to the present.
This new collection is based on the work of Hoyt and Schatten (Solar Phys. 179, 189, 1998) …
