List posts of a co-author in author.php

I use something like this:

global $coauthors_plus;
if (isset($coauthors_plus)) {
	$curauth = $coauthors_plus->get_coauthor_by( 'user_nicename', $author_name );
} else {
   	if(isset($_GET['author_name'])) :
      		$curauth = get_userdatabylogin($author_name);
      	else :
      		$curauth = get_userdata(intval($author));
  	endif;
}

echo $curauth->display_na

if (isset($coauthors_plus)) {
   echo get_the_post_thumbnail($curauth->ID,array(90,90) );
} else if(function_exists('get_avatar')) {
   echo get_avatar( $curauth->user_email, $size = '120' );
} 

if($curauth->description !="")
   echo $curauth->description;
}

if (have_posts()) : while (have_posts()) : the_post();
	$format = get_post_format();
	get_template_part( 'includes/post-formats/'.$format );
	if($format == '')
		get_template_part( 'includes/post-formats/standard' );
	 endwhile; else:
__('No post yet.', 'theme1965');
